Looking for some competitive basketball in St. Louis? Stop by Chaifetz Arena when the Saint Louis University Billikens are playing or get yourself to O'Fallon Park. After a decade or so of neglect, these five full outdoor courts were recently resurfaced and dressed up with new nets. For those feeling plucky, pickup games abound here. For the rest of us, O'Fallon Park offers plenty of space to sit and watch the action. You'll have to bring your own popcorn, though. Unlike Chaifetz, O'Fallon Park doesn't offer concessions.
