IC, I tried taking a lesson my first winter up here a I thought it would be a useful skill to have for winter emergencies. Unfortunately, with my eyesight, I found that the helmets restricted what peripheral vision I do have to dangerous levels.
I thought that was a pity as driving a sled actually sounded like fun. The eyesight/helmet thing is the same reason I never learned to ride a motorcycle.
Rhinelander/Eagle River has one of the largest networks of snowmobile trails in the USA. We are a winter sports hub for that reason.
