Yes, I commute in the winter, but not as often. It really depends on the road conditions, snow and ice are the worst, but to much sand can also cause some problems. As far as the cold is concerned, I started using the foot warmer pads that are sold in places like Home Depote for about $1.50. They help quite a bit.
The rest of me stays pretty warm with layers of bike clothing.
I working at a different plant location, (same company) so this will be my first winter at this site.
I also ride a recumbent, I'm thinking about switching to commuting with it at the end of October.
