One observation: in all my years living in a development, I don't think I've ever heard a generator running when the power went out. This time, I felt like I was the only one without a generator.
I dunno. I guess if you have small children and want to keep them warm in the winter, that's one thing, but I question the need on a relatively mild summer night. OTOH, there's the whole refrigerator question which becomes dire after 24 hours. I think I might get a (small) generator just for that purpose.
