I've had the "privilege?" of watching one pickup truck that rolled on out and completely submerged in salt water at Port Aransas, TX. The guy backed in, his boat floated off the trailer and when he saw it floating away, he jumped out of the truck without using the park brake, ran after the boat, even took off swimming after the boat and didn't notice where the truck and trailer were going until it was too late./w3tcompact/icons/laugh.gif And another time, at a local fresh water lake, I watched a guy who had just launched a small boat from a trailer behind a Ford Escort station wagon. When he went to pull out, he gunned the engine, killed the engine, rolled back while he was restarting it and after doing that 3 or 4 times, he had rolled back enough that the water was over the driver's seat by the time my brothers and I could get to him; manual transmission and he had never realized that he had it in the highest gear. We pulled him out and he got it started again; don't know how well it did after the interior dried out./w3tcompact/icons/laugh.gif
