Good job. If it were me in the canoe launching them, I likely would be among the launch group.
It got pretty hairy by the third one. Of course I saved the largest until the end. I thought I had it placed right where I wanted it, but it must have sat on part of one of the sunken cedar trees. If I do this again, I'll put rebar, or something through the bottom, to help stop the tip over. The rebar will go right through the side of my 40 yr old single layer ABS plastic canoe. It's an old "whitewater" the outfit that made them in the 70s went out if business shortly after that. They were also in the football helmet business. Lawsuits put them under., (I heard that from my BIL, could be bad info.)
