Are you sure they weren't Canadians posing as Oregonians? Given their shady rep around the globe, many a wily Canucker has swapped the maple leaf for the blue banner of the beaver, in order to keep a low profile. Naturally, this is the kind of shit they pull anyway, giving us Oregonians a bad name to boot.
My advice to you, my Eastern friend, would be to turn your piercing gaze northward. I hear Quebec is popular with the sketchier denizens of the Great White North.
