alright i wanna make a box, now where i live there is only to rails at my hill, and no boxes. I've never seen a box in real life. How do i make the top? Do i put 2 rails on the side and a plastic she in the middle, and how do i get the topsheet to stick, if i screw it in you'll catch on the screws, do i glue it or what?
I am a skier.
