Just thought of something.....Maybe he could talk to the land owner on the west side of the river????? I did see a pickup, over the weekend, right close to where the boat is.......maybe a pull from that side would loosen it from the log/rootball.......then it could be pulled to the east side of the river....

Heck, they might even be able to pull it right up the bank, on the west side of the river........or enough to get water out and float it down to the launch.......just a thought...
