You could see all of them in a drunken state... could be some sort of play on the different meanings of state. Also, they might not be the most famous places by those names, at least some of them.

For example, in addition to the most famous Death Valley in California, there's also a couple of stadiums and a section of freeway with that nickname. Plus a couple of films, which could be seen anywhere.
