Not "If" But "When and How"

As some of you may remember, several months ago I posted about gasoline powered generators. At the time, I was primarily concerned with keeping my family warm during an ice storm. However, after the Great Poop Scare of the previous week, I'm thinking that I'm one lightning strike or rain storm away from a very shitty house.

I know that generators are in the top ten list of things that depraved assholes like to steal from construction sites and private property in general. As such, I've been wondering how feasible it would be to install one in our crawlspace, have it directly wired into the electrical system (by a professional), and vent the exhaust out through the crawlspace wall. I mean, I suppose it could be done, but what are the chances we'd die of carbon monoxide poisoning? Or, would it be easier to build a camouflaged concrete bunker behind the house to lock it up in until we need it? Then, via an ass-load of extension cords, we could power the septic pump, a space heater, and a few lights?

I'll have to figure it out pretty soon, probably by January. It's always something isn't it?
