I've been riding to work, second shift, the ride in is great, coming home, not so great. The fairing on the GL really blocks the wind. My shins feel the wind the most. Last weekend I took a fairly long ride up over the ridge, there were a couple inches of snow on the ground, none on the road. I wore my new Tourmaster riding suit and was pretty comfortable for a couple hours, then the cold leaked in. When I got home I was cold.
I'll try to get out regularly during the winter. Not for long rides, and not if there's ice on the road, but on a nice day a short ride will do the bike and me a world of good.
