We do a lot of skiing and boarding around here - the snow here is outstanding. I boarded for several years, because my knee just could not stand the strain of skiing anymore. Boarding is much easier on the knees, I've found. But I never really got very good at it.

Then, about 10 years ago, I had a full knee replacement, and now YEAH!! I can ski again without totally blowing up my knee. Boarding was fun, for a while, but I like skiing better. Then again, I'm an old timer, so that figures, I suppose.
