Unfortunately, my wife happened to catch enough of the news to see something about a story of people rushing out to buy plastic and duct tape...uggg. I was afraid of that. Sorry, but I have no intention at the moment of being "one of those people." I figure if the nerve agents reach us out here in the 'burbs, we're fucked as it is. Of course, I have to convince my wife of this...surprisingly, she did not noodge me all night. She seemed to "get" this one. Our house is fairly old and full of holes, anyway. The odds of sealing any reasonable part of it off for even a few hours worth of time (how much time can you have anyway, with no air-recirculation?) is somewhere between slim and none - and Slim just left town.
