there's a bike park right next to the skatepark that has a shit ton of doubles and whatnot and it's always empty, probably because everyone is riding trails at galbraith (mini north shore), there's ladders, jumps, burms and tons of other shit up in there. skatepark is a five minute ride from campus and galbraith trail heads are close, too (one's probably a ten minute ride from campus, because it's uphill and the other trailhead is just south of lake padden, five minute car ride from campus).
there's a few pictures of galbraith here:
