No, Bart, Alan is so worried about all this that he probably ought to build a boat large enough that when the flood comes he can rescue all the folks on LuLa worried sick about global warming (or, since no such thing really seems to be happening, "climate change"). That's a lot of folks and elephants and bears and giraffes and . . . Oh, dogs. Lots of dogs and cats.
When I was a kid I spent my summers on a Michigan lake. Down in a corner of the lake was a boat: Bert Buell's boat. It was a houseboat Bert had built himself. Maybe Bert was as worried about the return of epeiric seas as Alan is. In any case, for at least fifteen years Bert Buell's boat sat there and never went anywhere. And the epeiric seas never returned during that whole period. And that's probably what would happen to Alan's boat. But at least he'd be ready.
