Just about anywhere is good, especially campus. Best thing to do is just take a day and go for a jog and look for spots. I train a lot at Bach, Mack, and Eberwhite a lot when i'm just drilling and strength training. Just head downtown around campus and keep an eye out. Buildings surrounding the diag have good spots, walk down the street in campus area and just walk the circumference of every building. For starting out though, just go to a local park and work on strength and conditioning, and practice vaults over and over.
