If It's Too Cold To Play In It, Then Play On It

Even swimmers like to ice skate.  Picture above is of ice skaters at Airmen Pond at Bowman Field in Williamsport (birdseye view of rink below).  Public skate times can be found here. 

It is interesting that every year the NHL holds one game (called the NHL Winter Classic) in an outside ice rink that attracts tens of thousands.  Williamsport is one upping the NHL by holding an ENTIRE season of hockey outside.  It is pretty cool to watch the Williamsport Outlaws (Federation Hockey League, see here) play a night game under the lights and stars.  If you are going, bring some blankets and something to sit on (bleachers are cold in the winter)
