The older I get, the less impressed I am by these modern marvels. I used to work so I could have a nice car. Now I have a dependable car so I can work. When I was 20, working to buy electronic devices seemed brilliant! (yay capitalism) These days, a 50" plasma tv isn't worthy of my hard earned money.
If someone came up to me and asked "What do you want?", I'd have to answer, "A little bit of peace." Now, that's what I'm working to buy. Turns out it's by far the most expensive thing I've ever worked for.
Joe, tell me what you know about building stone houses. I actually talked with my uncle (an architecht about it.) He tells me there are no stone quarries in MS, so I'll have to import some or move.
I actually have a small piece of property that's surrounded by hundreds of acres owned by a timber company for growing timber. So, I hope that for the next several decades at least, it will remain remote.
Sherbs, my dream of serenity doesn't involve a lot of shotgun vigils!

But I get what you are saying. In the event that terrorist activity actually DOES drive us away from technology and into the brush, we may find ourselves in the situation you described. That would actually be chaos to me, but like you, I know I could take care of myself and my family. I imagine many would sit around wringing their hands waiting for the government to rescue them.
But airports shutting down doesn't even register on my radar of inconveniences. If Piggly Wiggly doesn't get in a shipment of groceries, I could still eat! True, I hope I never had to resort to a diet of raccoons, squirrels, rabbits and poke salad. But I've eaten all those things before. It's mighty tollerable. LOL
