Temps around 30F. Okay I broke down and wore full-length lycra on my legs, and gloves.

Didn't get hot, so it was okay. Interesting wind, alternating from "side" to "tail", at one point pushing my little knobby-tired Trek to 18MPH without me even working at it.
Weird thing: I rounded a bend and there was a big pickup truck on the MUP. It was following a small group of runners, and it had Mississippi plates (this is Vermont). Bizarre. I turned on my L&M 13W headlight and he moved off the pavement to make room for me. I dropped him hard. Heh heh. I passed more runners after that, so I'm assuming it was some sort of support vehicle for a club.
