I grew up in a very old farmhouse, built before 1913, and built like a fence. Posts with long stringers between, with 1x14 inch redwood planks put up on both sides, like a fence. When I think of all that redwood and the size, I can imagine the size of the tree required to cut that much knot free, clear lumber. I wish we'd salvaged all of it, but at that time we didn't realize its true value.
Has anyone noticed how skinny all the workers in old pictures are? I can understand why when I think of the effort it would take to take down that large of a tree by hand. Hard work!
The more I do, the less I accomplish.
