When the next National Basketball Association superstar is blowing up, fans will all want to tell stories about how they saw him way back when. And if your story includes said superstar playing pro-am ball in a gym best known for being the home of roller derby — you win. SF Bay Area Pro-Am offers fans the chance to watch high-quality men's and women's basketball games for the same price as blowing your nose without a tissue: free. Past stars who have played in the summer league include Steve Nash, Jason Kidd, Gary Payton, Tim Hardaway, Robert Parish, and the legendary Kurt Rambis.
