I bet, we could write a series of paperbacks. Forgotten drain plugs, forgot the battery, forgot the transom straps. But, I think the most excruciating one was about 30 years ago at Fisherman's Cove at the Narrows, some guy who had obviously never practiced, backed up his boat with the motor tilted up. That wasn't the bad part, it was when he rammed the prop clean through the other guys pick up door. Needless to say it was pretty close to an all out rumble.
