Street basketball is a great way to blow off steam in an informal setting. It doesn't require a set number of players, fancy equipment or a referee – just a hoop, a ball and at least two people with the ambition to win!
There are several places to shoot hoops in Austin, but my favorite spot is in the park near my house. It's close to home, not too crowded and kept in good shape. I've gotten to know the regulars there pretty well by now, and several of us meet every Friday for an after-work game of four-on-four streetball on the half court.
