Similar to pad 7, pad 2 was another one that needed a retaining wall to prevent dirt from covering the hole. After clearing and leveling the area, we used 4 x 8 wood planks to create the retaining wall. This time we needed to go 4 high. Pad 2 also had another challenge. The pad was at the bottom of a steep hill. We were able to carry or slide the tools down the hill by placing them on a tarp and pulling it down the slope. We cut notches in the wood, and secured them together with wood screws. When we were finished, it was time to fill with sand. It took about two-and-a-half bags of 1,000 pound bags of sand to fill the frame.
