Some friends and i went bush flying in east Oregon. Through some canyons and over lakes. While going to land on the edge of a lake, I decided to skim the water. That didn't work out too well for me. It ended up nose over in the lake and sank to the bottom. Its a good thing i had friends to get me home. We left the plane sunk in the water till summer came. That lake dries out every summer. So when summer hit we went back and retreived it. Had to replace a couple parts and rehaul the engine. One of the seats didnt survive so had to replace one of them with what i could find.
