see who can do as many butters down the run and they only count if you can do them normal left and right, and then switch left and right.
Also the game GNAR, SKI, or STOMP are all like SKATE or HORSE just on skis and if you are evenly matched it gets really fun to see who can do the weirdest trick and see if the others can do the same.
jib anything and everything.
i'm definately doing that this year with my buddies. sounds sick
