Replying to Backyard Starter Kit

I was wonder what would have to go into making a backyard rail for over the summer. I was thinking of trying to make one but have a lack of knowledge about it. Or even if it is worth building one.

I know you can use PVC piping, however do you have to do something to it in order to have your skis actually slide on it?

Other than PVC piping, what else do people use?

For the runway and landing, what type of material did you use? I read you can use astroturf (expensive) or some landscaping material (I know what it is but unsure about the name).

Any help is much appreciated!
