lexan very expensive you can get 3x3 sheets at home depot for like 30-40$ so be perpared to spend money for that and thats about the exact demensions as my box and its a little beastly for summer width but thats a good length
fence slides very well just double layer it and its faster then normal i got it at tractor supply co. since home depot was sold out and thx for makin that pic work

make sure you have something hard under the carpet cause that helps with speed and if its wood it gets wet and helps the carpet stay wet but id wonder about the tarps if anyones done this id like to know too
id make it high ecnough to use without snowgel incase you dont have it at all times. id just move it farther away and use less snowgel when you use it. that saves snowgel and makes it useable without it
what size pipes are you using? if you want a more like a rail do 2 if you want it more like a box do 3 but the size of the pipes is what will make it a box or rail
i have a triple ........ but i made it to be a box 3 2inch pipes........
id build 15ft rails cause 10 will be shorter then you think....... but for a 10-15ft rail go like 8ft high then just test different angles of the slope down to make it faster or slower
maby build a multi-level drop in one at 8-10ft for your rail other like 15ft for the jump except a steper incline for the highest 5ft part.........but this would be tricky to build
