Took down 5 good sized Oaks Saturday, 4 were 20" at chest height. Had my cousins climber climb for me. Every thing stayed on the ground, but had to be trimmed and bucked so customer could move it. Put in a good 8 hour day. I cramped up all night long. My hands cramped from holding and starting the saw, neck from looking up, and legs from stepping over brush. Left knee doesn't bend well yet, but that leg didn't cramp much. I really wanted some of the wood but their yard is a swamp, and would have to move it over 100 yards. They are letting it rot and burning in an outside fire pit, Joe.
