well, actually according to definition, portland, OR is most certainly a metropolis. (no specific population number has to be met to confer the honor of "metropolis", it simply has to be the center of activity for a larger region.) A small sized city is no larger than 200,000 at the very most, and portland is more than twice that size. And after living and owning a car in Portland, I know for a fact you can't make it across town in 20 minutes - although that would have been nice. Semantics maybe, but i thought you might like to know.
