I mean the other 2 countries, Canada and Mexico, how similar are both of them to United States?? Both countries have a similar economy and democracy etc, and I think those two countries share things like supermarkets, stores, etc. I suppose the cultural differences are not a lot, that is very nice.
Coastal BC west of the cascades is very similar to Puget Sound region and Portland. Anywhere east of Whistler and Chilliwack is much more rural religious and conservative, similar to central and eastern Washington. Another cultural oddity about inland BC - Kelowna and Kamloops have some of the most violent and active Hells Angels chapters.
