Though Play It Again Sports is a chain, the stores are also franchised, so this particular PIAS, owned and operated by Rich Tere, has the Miamian in mind. The store operates on the principle that after you take the first few checks to the upper lip on the rough grass in the field hockey tournament or sprain your wrist breaking a Rollerblading fall, you'll rethink those weekend passions for something along the lines of speed walking ... and you'll want to unload that gear. At Play It Again, you can buy, sell, or trade everything from boxing gloves to tennis rackets to golf clubs and even luge helmets. The prices are right, so by the time the summer heat drives you to reconsider the walking path, you can pick up a gently used bowling ball -- cheap.
