We are.
For the very reasons you mentioned.
Tell them to watch for a cropduster .... or 5 guys with rifles could have a field day along that highway now.
To be honest it looks like a perfect way to trap thousands in a contained area ... and fallout from Baltimore would hit DC .. (worst case scenario)
Was actually over in Annapolis when it happened (didn't look for or notice the cloud) and just got back home, but heard about it on the radio in the car.
Actually sorta surprised at how few posts this thread has, but on the way back I was wondering how nutty people would be about hoping it was terrorism...I have to say that FR has greatly improved in this respect in the last 6-12 months; had this happened a year ago there would have been a half-dozen posters absolutely insisting it was a terror attack, and that anyone who didn't believe it was a terror attack was an AQ sympathizer (which never quite made any sense, but it did happen quite often.) Actually, I suspect most of those types (can't remember the screennames) have left FR.
