Had the same thing happen to me. Was fishing by myself and sat down to retie. Felt the boat bounce of a few stumps and then stop. After getting bait ready I decided to grab a sandwich and get my black lights out and set up while stopped. A boat came thru pass and put out a big wake and it wedged me in tight. It wasnt between two stumps but two trees. I tryied to get out with trolling motor then the big motor and nothing. I ended up putting my feet on one tree and my sholder on the other. Had to get about five feet above boat and push. The first time it broke free it only went deeper in. I then hooked a bungie strap from tree to the front light and pushed again and the boat broke free. Never will I do that again.
Thanks for the memory jog. I had forgot about that.
