No matter the season, Long Island's recreational basketball leagues are looking for free agents of all ages and skills.

You can form your own team, join an existing one or just show up for a pickup game. League play generally involves eight games and a playoff; you also might win a trophy or get a team jersey.

The benefits of recreational team basketball? Well, there's camaraderie, and a chance to see if you've got game. And you may sweat yourself into improved cardiovascular health. "Aerobically, there's nothing better," says Jack Ferguson of the L.I. Hoops Adult Basketball League.

Here's where to get your hands on the ball.
