I love night commuting. 4:00 a.m. to 5:30 a.m. is my favorite time. The drunks are home, and I have the streets to myself. I have an HID on the front, and two blinkies on the back. I wear an ANSI lime vest (like the construction workers wear), and I put reflective strips around my ankes. I use those velcro things designed to keep pant cuffs out of the chain.
It's fun even when it's cold. When I'm geared out for 0F, I have so much on I feel like a tank methodically pedalling down the road.
