What do you know about British Columbia?

In alot of ways it's pretty similar to Washington. The coast is alot different then the inland valleys, the population is dominated by coastal cities (ie: Seattle and Vancouver), lots of irrigated agriculture in the dry valleys, etc. By virtue of location Washington has more fertile valleys to grow crops in (the Yakima Valley is alot more fertile than anything in interior BC.. the Okanagan grows alot too but that is also shared with the US).

I'd say in terms of geography the main difference is that BC is bigger, and the mountains are a little bigger in the interior. On the coast there really is not much north of Vancouver in terms of valleys, particularly valleys suited for development, so you don't see alot of cities and towns north of Vancouver along the coastline. Much more mountainous then it is along Washington's coastline (it's actually really similar to the Olympic peninsula, but just imagine that stretchted out all the way up to the panhandle of Alaska). BC has more varied climates, biospheres but that is moreso due to sheer size.

Washington has more people than BC does. Some of this is attirbuted to more geographical obstacles in BC for development, some of it has to do with the deep waters of puget sound favouring shipping to Seattle over Vancouver.... some of it may have to do with Washington being "settled" earlier than most of BC. In terms of visible minorities BC has more proportionally than Washington does and of slightly different composition (especially in the interior where in WAshington you have lots of Mexican migrants, whereas in BC it's more South or East Asian), but that difference is not huge. The greater Vancouver area accounts for about 60 - 65% of the total population of BC so it's very concentrated in the fraser Valley, kind of like how Washington's populations is mostly concentrated in Seattle.

I'd recommend going to Tofino, BC on Vancouver Island (super chilled out surf town, really cool), or if you go to the interior go to Nelson, BC in the Kootenays. It's also really nice. Overall, Washington and BC are similar but there are some differences. I would say from my subjective experience, BC is a little less "commercialized" than Washington... you don't get line ups to see natural wonders like you do in Washington and it's a little more "wild" in BC especially in the interior. But that's just my opinion.

Yanks use it as Hollywood North. The X-files was filmed there. I think. Idk. I never could stand that show and hardly ever saw a snippet of a scene here and there, if that much at all. Oh and I think there's where the cool hanging bridge is at, I forgot the name, Capotino or sthg, I will forget it again after I read it LOL!!

There's still some cool trees standing - old-growth temperate rainforest

It's very expensive to buy a house there.

Its bigger than Washington.
