It was fall of 1994 at our Western Alaska camp. The day started out as one of those beautiful September days. I had been checking spike camps that morning with the Super Cub. One of the camps had a moose down so I needed to pick up a couple of packers and some supplies. I landed at my strip, taxied the plane into the tie down location, got out and faced into the wind. Most of the morning the wind had been blowing about 20 mph and the weather report never indicated anything about strong winds. It takes me about 10 minutes to tie the plane down and 5 minutes to untie it. Since, I was only going to be at the camp, which was on the other side of the lake for about 30 minutes, I decided to save time and not tie the plane down. I always leave the plane untied when I land at spike camps so there was no difference.
