And it's done. Or at least, as done as it's going to be. In the morning, we just need to install new batteries and do a quick check to ensure that everything is still running well and that nothing spontaneously combusted overnight. Then, the competition will tell the tale.
On a perhaps interesting (and only vaguely related) note, the difference in traffic on the streets between say midnight and 3 am is striking. I think I passed a total of ten cars biking home. The lights all worked in my favor, too. This made it one of my fastest trips home yet.
Now, for sleep.
