Thanks for the site, FairOpinion. However, I find that site nearly useless. I gain nothing from this other than "watch TV" or "listen to the radio." I want to be proactive.
I figured they just give you general info.
You can try doing searches, I think there is more info on the net, including places selling protective equipments, etc.
I personally don't know of any, but I am sure they are out there, you just have to be careful to sort through them.
I think, considering the potential magnitude of the threat, we all should spend some time getting ready for all eventualities.
