My wife and I were talking about that. After 9-11 and now this, it really gives you perspective on how bad things can get. We were talking last night about how we still really need to get at least one long gun for defense. And not only that, I'm starting to think about solar panels. Be nice to have the capability to power at minimum our water pump and boiler. gas generators wont be much use if there's no gas. sucks to think about it now, but it'd suck even worse to be a refugee. we're in nj, but i can tell you, this is red country, and looters wouldn't live very long up here. no thanks to me tho. it's a hassle in nj to get guns, but i need to do it.
Get an AR-15 w/1000 rounds of ammo or a 12 gauge 870 remington with 250 rounds of buckshot. Either will get you through a tight situation.
A generator with an underground storage tank can run a house for days.
Important detail: Make darned sure the gas pump is powered by the generator and not by outside electricity!
