Replying to Summer Jump?

So.... Because I can't go to COC, can't go to new zealand, france, chile, or whatever, I wanted to know what you guys think about building a summer jump. This is without any snow, just using some home depot materials or whatever, and building it for setup on a hill near my house. I just wanted to know what you guys think about it, if its possible, how to do it, what to do it with, etc etc. If I decide I want to, I have like.... 300$ I don't mind spending on it right now if it would work well, so hit me up with your ideas. If I decide to do it and it does work, I will post something on newschoolers for everyone to see.
