Looks like he ground his way up there a bit!
I had a couple of buddies in high school who were running back from the Ivar's fireworks display accross the sound at about 1 AM. They had been drinking, and were going about 35 mph through the dark.... Well they made it about half way accross before running up on a log boom being towed to shelton! They hit the thing, caught air, and landed in the middle. Both were ok, but that was only by sheer luck. It was lucky that the boat was flat bottomed and didn't roll on them....
The tug operator checked on them, and they begged to be towed off, but instead they were towed all the way to shelton where the cops were waiting.
Ooops!
