Well, the first ride home from work was.... DARK!
It started out well enough riding off into the sunset on the W&OD. Starting on mile marker 24, heading for 44. The sun set fast and I switched on my little headlamp and rear, red blinky. The trail is pretty much a highway for deer at night and I must have seen 50 or so. The tend not to move out of the way until you are right up on them and then they faint right and jump left. today at work I heard stories of deer-bike accidents on the trail that ended unpleasantly for all involved.
Once the sun was down the going got a bit colder too and the wind picked up. And it got really, really dark.
