those're way easier on quarterpipes or tranny's w/ no coping. Try finding one of those first. If you do it once on one of those, you can do it a a hundred times, and that way, you're pretty much 2/3rds there, getting in and riding away, plus it gives you some experience guaging how fast you gotta go to not fall into that horrifying accidental disaster, or the equally horrifying, unexpected sw manny to slip-out onto the deck. You then just have to learn to pop harder on the dismount to unhook your wheels from the coping.
