I guess it depends on what your philosophy of dealing with an emergency is. I read something in another forum yesterday about making sure the home theater system was working after a hurricane - that's a personal choice, but it wouldn't be what I'd try to do. In the next paragraph, the person wrote about how they had cars stopping out front of the house and had people coming inside looking for things because their house was brightly lit while the rest of the neighborhood was dark. I'm not sure I want to attract that kind of attention.
