 Riding up the side of a wet river bank and coming back down to simulate a 1/4 pipe was also a new trick.Skimmers also propped up skimboards or wood planks on logs creating a ramp to jump off and do more tricks.In the late 1980s, skimmers advanced to building better rails and jumps and adapting more technical skateboard tricks, but they still used stuff found around their environment like shopping carts, road cones, trash cans, etc.
