A man and his wife go to visit their old home to see what the new owners have done. The pickup is driven down the driveway, thru the carport on to the steep boat ramp going down to the lake. As the pickup was come into the carport, the driver goes to hit the brake but hits the accelerator instead. Pickup shoots down the ramp, the driver realizes that they are going to go into the lake, turns sharply to the left hitting the concrete foundation flipping the pickup over on it's roof. Fortunately there were no major injuries. There was no way to get a wrecker down to the pickup so I set my wrecker at the carport which was about 150 feet from the pickup. John Raschke, owner of A-1 Wrecker thought we might be able to get his wrecker down the west side of the house and on to the lower level yard. I then winched the truck up the ramp until it was clear of the concrete foundation and steps. While I held the truck John uprighted the vehicle. I then winched the pickup up to the top and transported to my yard.
