so me and my friend want to session stuff in his backyard and we simply place a real wide pvc pipe he has on the ground and want to just session it like that..but the problem is it slides out from underneath us even on flat ground from ice on the grass or the snow..i thought about screwing stakes to a peice of wood..then screw the peice of wood in the pvc then just basically dig the stakes into the ground..soo help me out or tell me some ideas..
the pipe is like the one on the far left in this picture
