The synchronized swimming class at Portland Rec will teach you the synchro basics - like sculling, water wheel and the oyster - and you'll get to bust out those moves in every pool you come into contact with for the rest of your life. Nice.
These team sports are open to everyone, whatever your level, so even those of us who have never played rugby or volleyball or inner-tube water polo are invited to join in and give it a try. And have a hell of a good time learning a new sport.
