HA, now that's funny.
I remember looking at that thing every time we drove past as a kid, and always thinking, IF the guy ever finishes it, how are they going to get it out of there.
The road was only about as wide as the boat, and I mean both lanes, in a pretty busy area.
That's funny I knew exactly the boat you two were talking about immediately, and can still picture it.
It did look like it was made of concrete.
