Title says it all.
Made that setup a few years ago in a little over an hour. 1 jagged concrete-filled rusty basketball pole, 1 tree stump as the front of the rail holder, 1 jackstand with the basketball pole only resting on it, some carpet pad with water on it, 1 pallet for the jump, some 2 by 4s, and some nails.
My skis took so many coreshots on this abortion of a setup. Gotta love that 8th grade Washington DC trip hoodie and pajama pants too. That only adds to the sketchiness.
