One fairly significant difference between Seattle and Dallas/Fort Worth is that Seattle is a city of neighborhoods. Dallas and Fort Worth have areas, like Wedgwood, the Park Cities, and Fort Worth's Cultural District, but none of these are really neighborhoods in the same way that Seattle has neighborhoods. Many of Seattle's neighborhoods were actually once their own towns that became annexed by the city so the neighborhoods all developed somewhat independently when they were young and were kept strong through streetcar connections. Even now that those individual towns are part of Seattle, they still maintain their own unique identity, made up of their own churches, stores, farmer's markets and festivals. From what I gather, people tend to shop, eat, and spend time in their own neighborhoods and don't go to different parts of town as much, which seems to develop a greater sense of community, from what I can tell.

This neighborhood-centric attitude extends to how people think of places. In D/FW, when giving directions, something would be off of a certain street, ("it's off of Hulen near Central Market") or near a landmark ("it's over by Ridgmar mall"). But here, when explaining where something is, people are much more likely to first tell you the neighborhood, then the street and cross street ("It's in Capitol Hill, at Broadway and Madison").

I can't say that our neighborhood (South Lake Union) has a strong sense of community, but when anything is happening in our neighborhood, it's referred to by neighborhood first, before the streets or landmarks are mentioned. This hasn't been a big adjustment by itself, but it's just kind of an interesting difference.
