you need a couple of things. a rail, which you can make out of pvc piping. mount that on a 2x4 and then attach legs to it for your rail. make shure that it has crosshathching so that it doesnt faall apart. then youll need a turf mat to slide on. easy find at home depot or just steal it from your local athletic complex. then you need a ramp or hill to get speed. if you have a hill, great. i didnt so i built a platform out of decking posts, 2x4's and plywood. mines about six feet tall. then i made a ramp down out of 2x4's and playwood and then put a transition on it so i could jump on to the rail. look at my pictures to see what it looks like.
