I'm 10,000 miles (give or take a few) away from home. I have a wife and three kids (13, 3, and 10mo.). Their awareness and preparation level is decent, considering the situation. My major concern is if there is an immediate IDLH-type emergency and there is no way of communication, what would you think would be the best way to keep your sanity until you get confirmation that everyone is OK? <---Thinks too much when bored.
