Let's say there is a new extreme sports training center being built in your area and you had input on the design, what would you want to have in it? There will be ramps big enough to double into a foam pit, Olympic style trampolines, a jib line, mini ramps, and bowls for skating, dirt jumps, and a concrete street course.
Knowing that, what are your favorite features to hit? The most fun? Most challenging? Best to learn on? If you have been to such a place (read: Woodward, Windells, Whistler) and did not like something, what was it? What would you change about those places?
