Young singles who know how to make a cowboy hat and denims look bad-ass strut their stuff on the Rockin Rodeo dance floor at Graham Central Station in Tempe's auto mall district. Part of a Texas-based chain of megaclub "entertainment complexes," Graham Central Station combines four clubs and four distinct clubbing populations -- retro, karaoke, urban dance and country -- under one roof. But it's the country club that gets the Odessa chain's fullest attention, featuring a mechanical bull and the complex's biggest dance floor. Recently, GCS added Thursday night Rage in the Cage fights to its weekly mix, promising "Mayhem at the Station," along with 99-cent longnecks and beginner country swing lessons. Giddy up!
