My hobby is experimenting with designs for shooting pits.
Here is my second design. It is two shooting pits, facing each other. As in horseshoes, you stand at one end and throw into the opposite pit. Then you walk to the opposite pit, pick up your boules, and throw them back toward the other pit.
Here is a closer view of one of the shooting pits.
I built it out of scrap 2x4s but I think one-inch thick boards would work perfectly well. The white sheets on the ground are a plastic material called Plas-Tek. They are sold as construction material to line showers and should be available at your local Home Depot or Lowe’s. They come in 4’x8′ sheets, about 1/8″ thick, and cost about $20 each.
The pit is out-of-doors, so I raised the sideboards about an inch off the ground. That allows rain to drain off, and allows me to sweep dust and fallen leaves under the sideboards and off of the court.
When I pick up the boules I put them in a white plastic bucket on brick “towers” where they will be easy to reach as I throw.
