Eastern WA is warmer and dryer in summer, colder and wetter in the winter. We have lots of fruit trees and wineries though.
Generally speaking, Eastern WA is conservitive to libertarian, west side is liberal. Ron Paul won 9 counties in WA, 8 of them east of the mountains.
OC without a license is very liberal, including into the state house in Oly...and our CPL is very easy to obtain.
Normal places you may frequent that are restricted are all marked "over 21 only" (true bars) You may go, eat and drink at a retaurant that serves, you just can't take your carry into the "over 21 only" bar area.
With a CPL you can carry on school grounds, but not in the building, and you cannot carry into a court, but they are required to have metal detectors and a lock box for your weapon at the entrence to the prohibited area. RCW 9.41 is the WA law.
ORS 166 is the Oregon firearms law. OR isn't too bad, especially anwhere away from Portland, with Eastern OR being much more free. With an OR CHL you can OC or CC most anywhere including public buildings. Oh yes, WA has a partial restriction on full auto, OR does not. If you are into full auto OR would be better, if you do not care about full auto...I think WA is better.
BTW: I calculated it awhile back, maybe a bit different now,,,,but when I did the calculation for myself, somewhere between $25k and $30k: if you make less than that, OR with their no sales tax is better, if you make more, WA is generally better. (I would never transfer a weapon through an FFL in Seattle, ever, their sales tax is a full 2% more than ours over here in Okanogan Co.)
