San Diego was far more different than Austin, TX, and considerably different than Ithaca, NY.

I'm still legally a WA resident, and having done a lot of time around Seattle, Everett, Bellingham, and Vancouver, I can tell you there are a lot of similarities. Seattle doesn't have the Aberdeen Mall, but in terms of attitude there isn't anything you can't find in Seattle.

Once you get out of the city, guns, religion, and skepticism of the urbanites is just as common as in the US -- standard Urban-Rural divide. Hell, even the "fly-over" provinces are conservative, just like in the US.
