The University of Arizona is one of the few places in town where you can find a large patch of grass to play a game of croquet, Frisbee or touch football, but that's not all the campus has to offer. (And no, we're not talking about the cheerleaders.) The UA has an arboretum of local and exotic plants, from the Arizona mesquite to the Australian weeping bottlebrush. Take a virtual tour on their Web site and impress your friends by knowing so much about nature. One more thing: Cheerleaders dig green.
