I would and do ride in the winter but I also use the trainer a lot. When the plows are out, the roads are covered and Icy I ride indoors. When dry I ride outside. For me not riding outside is more of a hassle factor, cleaning the bike of so much grit in subzero temps is just no fun. I don't have a good or heated work area. So the preponderance of winter miles are inside. But I do love getting out some.
