Not much reason to flee here in Central Washington. Brush fires here aren't like SoCal, so even though we get them, they aren't much of a threat. Weather patterns are pretty favorable. Geology not conducive to seismic activity, though if Oregon Cascade volcanos went off we might get some ash. Hanford is too passe to be much of a terrorist target, and they have burnt up most of the chem stockpile at Umatilla now. About the only thing that I would be concerned with is if we lost Priest Rapids dam, it'd flood the USTs at Hanford and send a lot of rad waste etc down to Portland. Fortunately getting to high ground here would be easy enough, and plenty of warnings before the wall o' water got to us to evade safely. I could be 1,000 feet higher than I am right now in less than 5 minutes.
