Its a fun activity and being outdoors lets you experience the changing weather. Then there is night skating which is a blast also. The air is cooler the stars are out and there you are enjoying it all.
If you want to experience a wilder side of ice skating you can try June Lake. When the lake is frozen you can see the locals on the lake skating. I personally am not comfortable with this as the ice is not groomed and falling is a reality that I don't want to deal with. Also I'm not too keen on the idea of falling through the ice if it is not frozen completely. Call me a fair weather ice skater if you will. In any case, depending on your comfort level ice skating is fun for all ages especially for adults as I think it brings out the kid in all of us. You find yourself laughing, relaxing and having fun.
