Looks like they built a frame and used real rocks on some portions. Might be a good alternative to having it indoors all year around. Have it inthe garage in the winter, then move it outside in the summer!:)

That is a ery nice course re working my indoor course here in wisconsin sure is nice when the wind chill kicks your azz and your indoors soaking up the heat
