I agree that natural forces are more likely to cause major disruptions than bad guys. I've experienced more than a couple of hurricanes (I got married the weekend Hurricane Agnes hit the east coast, the darn thing chased us for a week on our honeymoon to New England).

Seeker, doesn't the New Cannan fault line run through part of Ohio? The first earthquake I experienced was in South Bend, Indiana.

The threat of a nuke power plant gone bad is a consideration. I live about 90 miles down river from Three Mile Island (actually have been there a couple of times not long after the incident). Duct tape anyone?

But the most frequent and pain-in-the-kazoo problem is snow and ice storms. I'd appreciate recommendations about back-up power systems.

I think the question we all want to ask ourselves is not have we done enough (and buying gear is fun) but have we thought about how to react to situtations and plan accordingly. One of my favorite sayings is "In a crisis you don't rise to your level of expectations, you fall to your level of training."
