Snowshoeing on the bike trails to the south of Reservoir Road. I chose snowshoes since I was pretty sure that most of the trails would not yet have been biked by the fat-tire guys. But as I started out, much to my surprise, I only went about 50' and there was a groomed trail waiting for me! True, it hadn't been biked recently, but it was flat, and fairly firm underfoot. Still hard work on the climbs though.
Can't complain about a groomed bike trail!
