Make a 6 foot tall drop in, 12 foot long by like a foot high rail and BOOM   Standard summer setup for you to spend your summer on. If you are using a hill, you probably wont need as big a drop in. For example, I have a 4 foot drop in on a small hill, with a PVC drop in, some astroturf into a 2 or 3 foot high rail, then some turf on the landing. Its sketchy as fuck because its so narrow, so I would advise you to cough up a little extra for more turf, it might be a waste but for me I learn better when I feel safer, so I hit my friends alot more than mine, about the width of a pallet will be plenty
