Los Angeles, Tokyo, and New York City are cyberpunk/biopunk. London, Paris, and older New York is steampunk/clockpunk, but where do you think dieselpunk would have likely been set? I think since dieselpunk is all about the petroleum power based technocratic society wouldn't Detroit be the logical place? Chicago, Cleavland, and Cincinnati are also good choices for setting. Don't mind me, I'm just thinking out loud...er...well you know what I mean.
