For me, it came along like this, My brother had traded for an old boat that needed way to much work, and sat in the field across from my shop for near a decade. I asked him what he was going to do with it, as I was mowing and cutting trees that were growing up around it. He said he was going to get rid of it, and if I could do anything with it, to go ahead. In the same time period, I had committed to building a tree fort for/with my grandson. Well, Tree boat was born as an inexpensive way to do both a tree fort and clean up the field of the old boat.
