Every year, I think that the extra hour of sleep is going to do something magical for me (I'm naturally nocturnal). Nope - I still feel like trash when the alarm clocks go off, and now get to spend an extra hour of my awake time in darkness!
I've got a handful of lights ready for the commute home (which has been half dark lately, anyway). It's the first year I've done this particular commute, so I will be experimenting with the dark trail vs. dark roads. I think I trust the dark roads more: drivers are predictably distracted, whereas the critters on the trail are not. If only I could get the deer, bunnies, snakes, and frogs to start using headlights...
