None of the poll options fit me completely.

I won't ride in the rain or on icy roads, but I'll ride all winter when the roads are dry, even if it's 20F degrees out.

I too work at home, so I have the advantage of being able to schedule midday rides during the daylight and then work partly in the evening to make up for it. I really feel for those of you who can't get out in the daylight on weekdays. That must be hard.

If the roads are snowy or icey, I do 5 mile fitness walks that loop through all the pretty streets in my town. I also go snowshoeing on nature conservancy lands nearby if we get 8" of snow or more.
I also just bought a jump rope, which I am currently having fun with in the basement.
If all else fails I can always go to the rink and roller skate!

There's LOTS to do in the winter.
