And Batman The Animated Series placed it in Long Island. Gotham (and Metropolis, and every other DC fictional city) has moved around a TON over the last century. But, since No Man's Land in 1999, Gotham has since been more or less established to be in New Jersey. Now, setting aside I happen to be from here, New Jersey makes the most sense as a location IMO so I'm sticking with that one.
Oh, and for kicks, I made another map! This one is Burlington, Ocean, Gotham, and Atlantic counties. Gotham City is the one in red.
Where would Bludhaven be?
