This morning in John's Creek (about 20 miles north of RonH) it was mid 20's at 7:20 this morning. So it can get chilly.
Ron....I tell myself that I am saving gas money. I'm improving my health, and I am impressing the young ladies at the office . That last part may or may not be true, but it works for me
Also, just think about how much easier the rides in spring will be if you maintain your fitness rather having to rebuild it.
