Wherever the L&C-verse Metropolis is, it is highly unlikely to be in Kansas, since in the pilot, Clark encountered an electrical storm over Cleveland while he was flying between Metropolis and Smallville. In fact, that Cleveland thunderstorm would indicate that Metropolis is somewhere in the norteastern portion of the U.S.

It is located on Hob(b)'s Bay. The second 'B' is in parentheses because there is some controversy about its spelling. There is a sign with a single 'B' in Junior's underground lair, but elsewhere -- I can't recall where at the moment -- two 'b's are used. Of course, the spelling had been debated for centuries. In fact, it gave birth to one of Shakespeare's most famous lines. <Lynn ducks and runs>

I like to think of it as being in my home state of Delaware. (I've seen arguments that it should be around Dover -- which is located, coincidentally, enough, in *Kent* County.)

There was an extensive discussion of this topic in this thread .
