So a lot of people want a dryslope for their backyard or whatever but for me the problem was I live in Washington and the rain and forest around me would make astro-turf just soak up all the water and rot. so I found a way to avoid the usage of turf or carpet. This one works great for both skiers and snowboarders and is sturdy enough to not be sketchy. I also live in a fairly flat area so I couldn't just make a quick
I had an old wooden bunk bed that already had a ladder and everything so when I grew up and had no use for that we just used that to get the height we needed to get enough speed. Then I used at lot of marine-grade wood to make the rest of the ramp (which is optional) I wanted something that could withstand the elements the PNW offers. this wood is obviously much more expensive but if you live where I do its worth the extra money. I didn't realize it until after I had tested it out but since I had thought I would have trouble getting enough speed I raised the entire lower level about 8 inches and it made it so my rail was very high. but I trimmed the legs down so I couldn't straddle the rail.
I used a combination of m-snow and lattice fencing for mine because the fencing was extremely cheap(like $7) and I spent about $100 on the m-snow (taking advantage of sales). the fencing is good just for gaining speed but you have almost no control on it. so that's why I used the m-snow for the control and its reusable too. I was so pessimistic with the amount of speed I would get so now mine gives me almost too much speed. (learn from me) but thanks to this I don't need to use m-wax to get speed on this setup.
I don't have any pictures of the rail specifically but I made it so I have only 1 frame and I can just screw whatever rail I want to a 10 ft 2x4, then slide the 2x4 into the frame. I just use scrap pvc pipe attached to 2x4s for the rails and they certainly do the trick nicely and cheaply.
