BUMP because I was about to make this thread.
Did you guys ever find one?
Honestly all I need is someones backyard. I will come to your house and build a dry slope. There are construction sites everywhere here. I'm sure we could scrounge wood, and maybe pvc. My only setback is that I have no land, as I am living in Roskie hall right now.
if anyone wants a setup in their yard, please PM me, I will come and build it, if I can session it whenever.
