Ice Skate at an Olympic Training Center
UD is home to some of the top notch world ice skating athletes, and has a wonderful public ice rink right next to the football stadium. For a couple of bucks, you can go and skate on the same ice that many of these people train on. I believe there are also times when the public can go watch the sessions, but I don't know all the details of this. A totally fun family and friends activity!
