Dagny,
Terrorist wise, a geiger counter would mean exposing yourself to take readings.
In a WW III scenario, given your location, I do not think you will be needing one.
Sorry, I deal in the truth.
WWIII -- you're right, I certainly would not be needing a Geiger. Would be part of the mushroom cloud(s).
Probably won't be needing one in the 10 kiloton single terrorist nuke scenario, either. But if I were home sick that day, and in the basement when it happened....
I don't suppose weather.com has the kind of info. And my cable Internet would probably be a bit slow.... or gone.
