If I get a chance (which is not likely tonight or tomorrow... sigh) I have been meaning to call in on this.
Maybe it makes sense for Sam since he has a big tree farm in Texas, but for most people it doesn't make sense to move there.
For one thing, NH is highly agricultural.
For another, our economy is holding up well compared to other states.
For another, it doesn't matter where you live -- having emergency supplies, gold/silver, and investments in dividends-paying non-dollar assets is a good idea no matter where you live.
For another, there are a number of monetary- and economic-related bills about to come down the pipe. If even a few of them pass, we'll be in damn good shape. I won't spoil the surprise yet though.
(*) added -- on the show it sounded like a big issue Sam was concerned about was that people would know where he lived. I guess he's afraid of the Hungry Mob coming and stealing his food? That sounds just a tad paranoid to me. At any rate, as I like to point out, I have a nice plot of property and a looong line of sight from my house in every direction....
