I filled out as much info as I could on my signature, hope it will work for now. I am in the process of setting up my AGP. I had someone come out and get my pad leveled today. I have almost pure sand after removing all the grass and leveling. It is like walking in powder although it is solid. Do I still need to haul in sand to put under the liner? I am planning on spraying the area with Pramitol 25e tomorrow, which is a suppose to kill any vegatation for at least a year. I do have a few roots, but will pull and cut all before I try and put the liner down. My concern is doing this right the first time, I do not want to do it more than once.
