Is there a twin sized version? With a chemical attack, I think you'd want your kids to have one. Of course, the only way to communicate would be with the radio.
Plus, how many husbands would really want to be stuck in that thing with their wife during an emergency?
I can remember during a hurricane my mom telling my dad "How can you be so calm at a time like this?". My dad simply replied; "The windows are boarded up, we have food, we have water, the electricity is out, but we're okay and in case you didn't notice that the Hurricane outside is a natural event, and those events are controlled by a God. Last time I checked, I don't think you considered me a God. There is nothing more I can do."
