Thanks Barrettscv and Dudelsac for the questions/responses. One thing that I sometimes forget is that as long as I'm still riding, it doesn't matter if in cold weather I don't get 150 miles in for the week. Last year on a 10 degree day I pushed to get extra miles in and a hill climb and that was just dumb. Tell ya, though, I'm not doing snow this year. Drivers just panic and I could choose to ride roads with less traffic, but the truth is that a ride to work is going to involve riding through at least some high traffic roads. Better to just hit the trainer and burn some calories that way.
