Thursdays no good? Warwick too far? One night a week not enough?  Here's a couple other local groups that play:

 

Thursday 7:30 to 9 PM in Stratford, CT

 

CT SECONN 

Sunday 5-6 PM in East Lyme, CT

Friday 8:30-9:30 PM at UConn Avery Point

(Both pools are open prior to the game for swimming.

Get there early and warm-up!  Games start promptly!)

                              

Other nearby groups play around Boston and New York.  No matter where you are there's likely a game.  Check out the Underwater Hockey Tourist.  We found a game outside of London during vacation last summer.
