Replying to Summer park setup

I'm thinking about making a summer setup this winter, i have a flat spot behind my house. Any building plans for a drop in / jump? What materials are best?I dont really wanna spend 500 dollars on some damn msnow. I know plastic lattice is good for the drop in as well, but how much turf or whatever do i need for around the rail on the ground? I have a pvc rail i made and a fat pvc pipe, but don't really know how to build a frame for it.
