Well, I DID see this on the 7th...

Taken in Vancouver off WA-14.

I'd have to guess there were HUNDREDS of tanks, and some generators and hummers, coming into Portland from the east, on rail.

And I saw a few disabled camo-painted Hummers on 205 going South later that night (the pictures didn't turn out), but it caused a nice traffic jam.

I'd just dismissed it as an odd coincidence.

But on the heels of you mentioning possible drills... yeah.
