I'm making a backyard snowboard drop-in. It's an 8ft drop-in, and I have a few PVC rails to use with it. I want to make a jump, but not sure what I should do. Should I just make one out of snow, or make one out of wood that would be covered by the turf I'm using for the drop in? If I build one, it would be easier to exchange out features without having the jump to the side or having to rebuild it each time, but then I wouldn't be able to mess with the size like I would if I made it out of snow. Any ideas or opinions?
