What size jump?

learn them on snow. Summer set ups are for rails

I am gonna learn them on snow!!!!!!! I am just gonna pile snow on my dropin and get a crapload of speed Im not a dumb ass why the hell would I try them on turf. But if u could tell me what size jump that would be great too.

haha calm down, make it about waist+ high, then you may learn 5's but without decent grabs, the trick is not height but length, after the jump, you should make the flat part about 5 foot MINIMUM, the bigger the better, and the kicker should be a lil more than 4 feet long, also the angle and smoothness of the kicker is pretty important... It's pretty hard to make a jump but good luck anyways, it's gotta be real rugged

Thanks that really helped a lot and im propably gonna do what u said but instead of spending hours and hours building the jump entirely out of snow  Im  propably going to use ply wood and pile a ton of snow on it so i cant feel any wood at all its just easier that way. 

haha well good luck, it'd better have tons of support though and you're gonna need ALOT of wood =)
