Go WILD!  
And shorts?!?!  You'll likely NEVER see that on a pond here in MN.  
As a kid, we used to screw around on the rink behind my house (a parking lot flooded by the city), but I never did anything organized.  It's been since I was about 13 since I was on skates.  Don't even know if it would be easy to find them in clown sizes to fit me now.
Pond hockey is a way of life here in MN, though.  There's a big tourney every year.  It's a HUGE deal here, and there are literally hundreds of teams with over 1000 players. It's a cool things to see.
