I'm a Seattle native, but I lived in other places between 1994 and 2009 before moving back (to the suburbs). The difference between Seattle today and the Seattle I knew growing up is stark. Not all bad, by any means. But wow is it different.
Because things just change.
We didn't even have a big company come in or anything, it just changed over time one thing leading to another.
Get one of those coffee table books of historic Seattle pictures, and you can see the overwhelming constant change.
