Modified dock railing so canoe fits on the dock better. Dropped a 16" diameter maple that was in the shed turning area... trickiest felling job I've ever undertaken. Notched the two trunks above the "Y" (20 feet off the ground) VERY carefully so they would break off when the tree fell and tried to hang up in a big hemlock that the maple was pointed right at and was DEFINITELY going to hit. Plan worked perfectly! After lunch, spent time widening / smoothing the path downhill from the yellow jacket nest (that still seems to be alive and well). While trying to remove a 500 pound boulder from the path using logging chain and come-along, sort of kinda lost control of the rock, which proceeded majestically downhill through the trees. Thought for SURE it was going to take out the dock then sink the canoe moored alongside. Instead the rock hit the dock shack fair and square... but did NOT go through, though a couple of siding planks and a 2 x 4 stud are no longer intact. Having done enough damage for one day, went for a swim and canoe. Circled around a loon who seemed to be convinced that the echo from his call was another loon answering back.
