There is an upsetting account of a locker robber at the DCUSA Washington Sports Club over at Prince of Petworth. Not sure about the veracity of the story, but if it is true - then a guy with bolt cutters was able to walk by the front desk, into the men's locker room, and start stealing stuff.
I happen to know that a friend who goes during peak hours also frequently just blows right by the desk because there is a long line. No ID checked, nothing - she just gets away with barreling in there. Nice security, WSC.
