Steve,
Yes, when I was in Rochester -- late 70s/early 80s, I lived several miles off campus in an area that was mostly farm fileds, and cross country skiing became my favorite workout/decompression pastime. I would go out at late night and sometimes just ski aimlessly for hours. The genesee river also ran about 100 yards behind my apartment, and ehen it froze, I would also ski up and down the river. Good times -- back then when I could not only handle it, but actually enjoyed the cold and vigorous workout.
