I was at the lake on Saturday and 2 marina employees were pulling 2 plastic Jet Ski docks out of the water and on to a trailer. As they were pulling the docks out of the water, they started falling off the trailer. The driver backed the truck up so the other guy could put the docks back on. He stopped the truck, but the trailer kept on going - under water, and under the boat dock that was next to the ramp. The other guy was on the trailer as it went under and I thought I was going to have to go in after him.<br /><br />As they were sitting there trying to figure out how they were going to get out of the mess, the driver looked up and said "You'd think we've never heard of safety chains before!" <br /><br />I've done some really stupid things before, but thanks to those guys I will NEVER forget my safety chains.
