What is the eastern edge of the Pacific Northwest? (centers, agricultural)

[iPwn]

Is it the Cascades? Rockies? The border with the Dakotas?

Personally I'd say the Rockies is more of a boundary for the greater Pacific Northwest--which includes all of Oregon and Washington and most of Idaho---(although Eastern Idaho is probably closer to Utah and the Rocky Mountain states). The Cascades divides the Pac NW into 2 sections---the western portion is the more stereotypical image of the Northwest--big urban liberal centers, wet coastal weather, old logging towns--while east of the Cascades the greater Columbia Basin region is more of a high desert, agricultural, conservative region.

Some people throw in Western Montana in the Pacific Northwest as well--although culturally and geographically it feels fairly closer to the surrounding Rocky Mountain states as well...The further east you towards the Rockies, the less the influence of Seattle and Portland is felt and the more you're into the sphere of Denver and Salt Lake City as the dominant metros.

Cascades. Idaho, eastern WA and OR are the northwest but not the Pacific Northwest due to not being near the pacific. vastly different landscape (vegitation), climate, politics.

Pocatello, Idaho for more reasons than I can explain, but if I have to explain most probably wouldn't understand.

So Colorado is part of the PNW? Or is it too far south? How about Wyoming? Nah, I think both are too far east to be considered PNW.
