If you already bought a boat, how is a proper ramp going to break the bank?
We've all seen improvised solutions to problems that somehow miraculously work, all sorts of “hillbilly fixes” which are sometimes genuinely brilliant. But then sometimes you have this kind of thing, a couple of boards used in lieu of a proper boat ramp, with all of it ending in tragedy. It seems pretty obvious right from the beginning that something is going to go wrong with this, but it's such an amazingly bad idea that you can't actually tell how.
We just hope that the motorcycle didn't belong to some innocent person who wasn't involved in the obviously terrible planning of this whole caper.
