We have a TINY yard with no access to it unkless you go through the house. We had someone level the yard he used rocks last year we racked what we could used happy bottom and tarp but could still feel the rocks. We did get 2 small holes in the bottom. I need to put something stronger under it this year I was thinking of that fake crass carpet stuff I'm just not sure that will work I'm in need of ideas for this year.
