This is very interesting to read and a lot of food for thought about overheating when exerting yourself outdoors in winter. I lived for a while in Colorado and I regret I didn’t learn to snowshoe or cross-country ski. Snowshoeing sounds like a super-useful skill.
I know people up north use snowmobiles as a serious means of transportation, not recreation, but I think there must be a lot of risk for crashing into rocks, roots and stumps. And as with every other gasoline-powered vehicle, one day you may no longer be able to obtain gas.
