Why not buy one there? Just ride whatever in the summer and find out from locals there later on what's good. Visit the colorado forums here if you're really that inclined on riding one a couple of months and then packing it to take to college. I'd advise focusing on doing well in studies, not on fun with after school activities, especially if he's going to be a freshman.
