This is a video from Sandy, Utah of a boat trailer that becomes detached from the truck towing it (presumably as a result of user error) and proceeds to cruise down the highway by itself. As far as things a boat owner wants to see, I imagine this is at the very bottom of the list, along with ‘a gas gauge on E and no land in sight,”a hole in the bottom,’ and ‘the repo man.’
Thanks to my buddy Chris C, who agrees you can lead a boat to water, but you can’t make it not break free on the highway and crash into the median.
