I did a night ride last night. When we started it was about 55 degrees, but it was in the high 40s by the end. It didn't feel that cold because we were riding pretty hard.

I did learn something, though. When we got back to the cars, I started my engine and turned the heater. I let it warm up while I was putting my bike on the rack and changing my shoes. So it was nice and toasty for the drive home.
