Right on top of the old tires!We had to rebuild about a 1/3 of the leantoo attached to the goat barn. (where yearlings are) because a wind decided it was just easier to push the walls out. Roof was just handing there. So cut 4x4 and 6x6 for supports and used bobcat to lift the roof up enough to pound in the supports and then had to run into town to Menards for the siding. Used the same type as I used on the dairy barn. The yearling's were busy inspecting everything we did. Snuffeled the tools, wood, flatbed trailer, truck. And licked the truck. Then would come over and check out what we were doing. The old walls are now in the burn pit.
