Late afternoon and early evening was spent working on the tree house. Mom bought a bunch of planks for the cross beams and flooring. I had thought she’d get big 4×8 foot sheets of plywood, but she decided on planking. She also got some large metal spikes with 4×4 inch hollow tops. We, by which I mean I, pounded those in to the ground for two of the posts to keep the tree house from sliding away from the tree. We had a few alignment issues, but some pounding and “well, whatever” attitude brought us through to an officially declared successful conclusion.
