Matt Rachmiel sent me a picture of himself (taken by Jeremy Fishman) from a recent game at the Palestra. Located on the University of Pennsylvania ("Penn") campus in Philadelphia, the Palestra is one of the classic arenas in college basketball. It hosts games not only of the host school, which is in the Ivy League, but also selected games involving other Philly schools who, along with Penn, make up a collective known as the Big 5. Having previously sported painted-in keys, the Palestra has switched in recent years to empty ones.
UPDATE: August 2013: I (Alan Reifman) recently had a chance to visit Philadelphia and the University of Pennsylvania. I took some photos on campus, including of the Palestra. These are available on my college-campuses website.
