Chef, haven't I see pics of your bike with five or six lights on it? I'm curious how you missed the tree. Were you busy looking down at the twigs? I've learned to keep my eyes moving when riding in the dark. Since I can't see as far ahead at night as I can during the day, I try to spend more time looking down the road. I'm glad your fall wasn't catastrophic for you or the bike.

Edit: Oops, that cehoward. I have about the same amount of light: 700-800 on the bars, 400 on the helmet.
