Staying active in the winter is paramount for me. I mix it up with all sorts of strenuous winter activities. Snow shoeing, winter hikes, hitting the gym, chukar hunting, are my favorites, next year I'll give x-country skiing a try. All of the above is good for the body and mind. Staying consistent is the tough part, you gotta do it even when everything in you says no. Just lace em' up and go, your head will eventually get over it. When I was up in Alaska, I felt sorry for the people I knew who refused to give winter hobbies a try, to me, it's the best time of the year to be outside, seems like such a waste to not enjoy it. Here in Utah, I think the majority of people here are fairly active in the winter, I don't hear about cabin fever blues near as much as I did when I lived in the Midwest and Alaska.
