Yesterday after work, I drove to Congaree Park with my mom. From the status updates posted by the park, the peak firefly activity might have already been over. But even if so, I thought it would still be neat to be in a wilderness area after nightfall. Most other parks around here close at dusk. The forecast was for clear skies, so maybe there would also be a nice starry sky - here in town there is too much ambient light to see more than the brightest ones.

I looked up directions on how to drive there. I found that the Google Maps app has an option for downloading a zoomable map of a selected area. You can download maps of where you are planning to go using WiFi, and later on use them to navigate with GPS, without using any cellular data.

But my car also has a built-in navigator. So once I reached the outskirts of town, I turned it on and entered the address. I just wanted to be sure that I didn't miss the turn-off way down on Bluff Road. The expected route displayed on the screen, but once I started driving, it told me to turn right when I was certain that I should turn left. I stopped to verify on Google Maps that my memory was correct. Then I turned left and drove on. It started nagging "Turn left... recalculating", "Turn left ... recalculating", "Make a U-turn!" and so on and so on. I have no idea where it was trying to take me to. I wanted to turn it off, but neither my mom nor I could figure out how. Finally, after parking the car again and pressing a bunch of things on the screen, I turned it off.

The park's website had said that only flashlights with red filters or covers should be used, to avoid disturbing the fireflies. I happened to have a flashlight, plus a small BugLit flashlight, plus a headlamp, all with red LEDs. As my mom was coming too, I also brought 2 other flashlights, with red/pink cellophane covering the lights. But they weren't necessary. I only needed a flashlight on the way out. My mom only used the BugLit. The ones with the cellophane covers were still really way too bright anyway.

The parking lot was full already at the park, so I parked behind another car on the side of the road. It was already dusk. On the boardwalk, we walked past a lot of other people. We finally stopped at what seemed a good spot. (Beset by thoughts of "Maybe there are more fireflies further down. Or maybe there are fewer. Maybe that would only take us closer to that crying baby.") There were a lot of people noises. In the beginning, people were also constantly walking past behind us in both directions. Later on, much of that subsided and it was more peaceful. Surely there are places in the park where one could see fireflies too, without the crowds of people. But you'd need to be familiar with the park to know where to go.

There were a lot of fireflies, but not as many as I had hopefully envisioned. The peak activity must already be past. I didn't notice much synchronicity going on, although there were moments when a small group of them would flash at nearly the same time, and then go dark, and then do that again a few times. But there were also other fireflies around them doing their own thing, so it wasn't very obvious. The status posted by the park today said "Fireflies were again active last night (Friday, May 26). Visitors reported that separate groups of fireflies were synchronized (as opposed to all of them being synchronized together)." Maybe it was more obvious in other spots, than where we were standing.

When I see fireflies in my yard, the color of their flash is bright yellow. But the flash of the ones in the park was more white, like moonlight. (Maybe that was only because they were further away - the ones that were closer did have more color). But that white light made them look like twinkling stars in amongst the trees. Very magical. Twinkling moving stars. The kind of thing which might make you believe in fairies. In the moments when people were being quiet, you could hear the nighttime insect noises all around. There were occasional owl (I assume) calls. (Not hoot-hoot sounds. Though now checking YouTube for owl calls, it didn't sound like those, so maybe they weren't owls after all.)

We stayed after most other people had left. It was nicer then, without all the distractions, even though the twinkling fireflies seemed fainter by then, more misty and dreamlike. As we were on the way out, a few other people arrived. Perhaps they wanted to avoid the crowds too.

Other than the fireflies and the flashlights of people walking by, at ground-level it was quite dark. But looking up, you could see the sky a lighter blue between the dark outlines of trees. Even when we left, around 11pm, the sky still was that color. Not pitch black pierced by white stars, as I'd expect. Although the stars themselves were plentiful and beautiful. Does the night sky never really get black, even in the countryside? The moon was almost new, so the light wasn't from it. Maybe it was still ambient light from town; the park is only about half an hour away. Or do the stars always make the night sky seem a lighter color?

On the way out, I stopped at another small parking lot to get a better view of the sky. It was beautiful. I wasn't able to see the milky way (would it be overhead? I don't even know where to look). I think there was a pond nearby, but it was too dark to tell. There were some weird animal noises coming from the other side. I have no idea what it was. My mom guessed it might be a male deer. Maybe, based on this - the sound was sort of like that, though it's hard to remember now.

How can I have lived here this long, without having heard about this phenomenon before?

dirt ducts snakes

Last weekend I mucked about in 2 crawlspaces.

At the new house, one of the ducts had been loose and leaking out hot air (hopefully the reason for the high gas usage last month). An HVAC technician fixed it, but I wanted to look around to make sure there was nothing else obviously wrong-looking down there, and to get photos of everything.

I explored a part of the crawlspace with my high-intensity flashlight, headlamp, and camera. But a big low-hanging duct blocked my way to the other half of the crawlspace.

I wondered how the HVAC guy had managed it. Surely if a small person like me couldn't get through, even slithering on my belly... I suddenly wondered if there was another entrance into the crawlspace. There were no other entrances around the outside of the house. But in the garage closet, I found an access hatch. Bingo! Qiao knew about it, but I hadn't thought of asking him before-hand.

So I went in that way, found the duct that the HVAC guy had repaired, and took a bunch more photos.

Then my mom told me that she had been in her crawlspace unsuccessfully trying to find out where one replaces the filters. Since I was full of dirt from the other crawlspace anyway, I offered to take a look. The headroom in her crawlspace is somewhat better than at the other house. It turns out her system has an electronic air filter which has been turned off since she got the house. I'll have to go back to check what is inside the unit; when I was down there, I didn't realize that the front panel can be pulled off. It's possible the original cells may have been removed and replaced with a disposable filter - that may be why the switch was turned off.

There was a surprise in my mom's crawlspace: a long long long snake skin winding around the HVAC system. A snake must have shed its skin. Or maybe multiple snakes. Or maybe one snake multiple times. It was so long that I hope it wasn't a single shedding from a single snake.

Now I know to watch out for snakes when crawling around in crawlspaces.

I have discovered that the cloth paintings I made a long time ago glow fantastically under UV / black light, due to the fluorescent paints I used.

The 2nd one can be seen under regular light here.

I decided to send my cousins' kids in Germany some gifts for Christmas. So I stopped by Target and bought some neat stuff. 4 different cute little hats. A pseudo-bag (with a carrying handle and a tiny zipper compartment) in the shape of a "My Little Pony" with a rainbow-colored mane and tail. An orange yo-yo. Some stickers. 2 little toy cars. A "Pinpressions" toy.

I bought a red light saber for myself and Qiao. It lights up, has a motion sensor, and makes light-sabery noises! I couldn't resist.

After getting home, I realized that I had lost the yo-yo on the way to the checkout counter. It wasn't in my bags nor listed on the receipt. So yesterday I went back and bought 2 yo-yos (so that both older kids can have one; can a 6 year old handle a yo-yo?), another PinPressions toy (because they are so much fun), another My Little Pony bag (this one yellow with a pink mane)(because so cute), and another 2 little toy cars (so each kid could potentially have one).

I combed the one pony's mane as it was tangled. I'd like to try out the cars, as I didn't have any of those when I was a kid. Taking them out of their packages would reduce the shipping weight (excuse). I already took the yo-yos out of their packages. I'm tempted to try on the hats, but won't, to avoid stretching them out of shape.

Now if I would stop playing with the toys and actually pack them, the kids might possibly get them before January.

I was debating how to avoid gendering the gifts. Giving the boys My Little Pony bags might not go over so well, while giving them only to the girls could be unfair. The kids are still fairly young - 3 to 10 years old, and I don't know them well enough to know what kind of things they like. Two of the hats were from the boys' section, and two were from the girls' section. But the girls might not necessarily prefer the girl hats or vice versa.

The solution I decided on was to let the kids choose which items they want. Oldest kid can choose one item first, then younger kid can choose 1, and so on until everything is taken.
