I had the trailer hitch from hell story a million years ago on a steep ramp in the middle of winter, before cell phones at a remote lake here in the valley. I won't get into all the ugly and embarrassing details but I will say halfway down a steep ramp with a very heavy boat, I stopped to unplug the lights and disconnect the winch lines. The car wouldn't come out of park when I got back in, it was locked because of the downward pressure on the tranny. In any event, my genius friend and I blocked the trailer securely and began to take the trailer off the ball to relieve the pressure so we could get the car going. Yep the whole damn thing came loose, ran down the ramp, jumped a curb and came to stop in the rocks about thirty yards from the water. Six hours later, a tow truck and about 200.00, the boat was launched. Someday I will write up the details of this disaster and why two intelligent, grown men did such a thing. Ah the memories.
