Wow, I didn't know you were that old, Rip! Learn something new about you people all the time.
I've been skating about once a week this whole winter. It's alot more fun than running, it's lower impact, it works more muscles (especially your butt muscles, which is good). I just started buying hockey equipment (never played before) and I plan on doing the pickup games and maybe join a league. I've always wanted to play hockey, but never had the money until now.
The thing that has really stoked me about ice skating is that it has basically taught me how to do something else I've always wanted to do (but never had the money): It taught me how to ski! I went skiing this weekend for only the 3rd time ever, and literally, I took a test run down the bunny slope, realized what a waste that was, and immediately took the lift up to the big hills. I skied from 11 am until 9 pm, and my legs aren't even sore (while the rest of my friends quit at about 6 oclock). Now granted I'm by no means an expert skier, but the ice skating skills transitioned over very well. The two activities use alot of the same muscles and motions. So I guess it kills two birds with one stone.
