8 hours or so on a good powpow day, however i really like having a nice little 3-4 hour evening park sesh. doesn't kill your whole day (can still work, hit school, whatever), and you dont need to worry about eating arrangements or anything like that. just go out, rip with your buddies, and head home for a few brewskis. that's a perfect day for me, personally, and of course that's provided the hill isnt packed
