Yesterday I wore a sweater under my rain gear with winter gloves plus booties over my shoes, made for a hot commute. This morning was so nice (53F) I just pulled on a wool sweater over my work clothes & hit the road. My new batteries came yesterday so I had the 3 watt generator driven light plus a 10watt & 15watt headlight. First part of my commute is on dark country roads so the lights were great. Light traffic but still lots of careless drivers & had to take evasive action a couple times. Be careful out there.
