I'm not sure what the Seattle dot is in your map, but a resident of Seattle setup a terrorist training camp down there. He was really just a putz that thought he could make some money off of it.
But it looks like there were
6 terrorists down there in Portland. I think the city exists so that Seattlittes can see "See, we're not THAT liberal"
One of those six terrorists worked for Mayor Vera Katz in a security job.
I sometimes wonder if the PNW is safe from terror due to it being the backyard of the louses.
