Here in S. Florida we have a little experience with hurricane preparedness and year around tornado threats that overlaps with the Chem-Bio-Nuke scenario. I agree with johnbaker that some plastic sheeting (prefer 3 mil) and HD duct tape is a good investment. We have a designated safe room complete with plastic sheeting, duct tape, scissors, first aid kit, water, canned goods, decks of cards, and games for the kids. We keep seven 5 gallon water bottles in the house for our water cooler rotation, refilled by a reverse osmosis system. I think the term "family preparedness" is the key here. Why not do a few things to calm the nerves for your family? After 9-11 saw a web-site with basic supplies kept on hand by Israeli families and pretty much got it all for under $100.00. Hope to never need any of it. Main thing learned from Hurricane Andrew is it can take several days or even weeks for the government to get in to help. Regards, Tom
