Zac Efron wore a Cal Poly University tank during his latest trip to the gym in LA yesterday. The actor is originally from San Luis Obispo, where the college is located. He's been out and about on the West Coast since returning from NYC, where he sat front row during Fashion Week. He may have to head back east soon, though, to work on his next project. He's set to make a cameo in New Year's Eve, which has already started filming with Katherine Heigl in the Big Apple.
