That is what we are doing this weekend. Well dad pretty much has the plan already. We are going to go over it this weekend. Then he is going to butcher the grass, and then we are going to use his buddy's tiller and till the whole track. He has some drain tube we will use for the edges of the track.
I think we are going to use pallets and plywood for the base of the jumps and then cover those with about 4-6 inches of dirt. I think we, mainly him, have a good plan going.
