Groton is famous for the Electric Boat Company (I think that's the name), submarines manufactured there (at one
point, maybe now, too). I visited the Nautilus there.
Heck even the local AM radio station has the call letters
WSUB.
The last one, just christened, was cursed with the name Jimmy Carter.
It's a hunter killer sub of all things. God save its crew with that name on it.
