Interestingly enough way out here on the other side of the country, Seattle, is actually quite similar to Pittsburgh, just with Scandanavians and Asians instead of Italians, Irish and Germans..... Seriously though, Seattle is a hilly, neighborhood based town with a compact downtown and lots of green spaces due to the terrain. Everything's a little newer out here - not too much that goes back beyond the 1900's (a lot of what did exist burned down.....), so the look is not quite the same, but the feel is still quite similar.
(oh, but better weather - I don't miss the cold and snow, or the heat and humidity....)
