I've got to defend my West Virginia friends here just a little bit. It's not exactly Florida. If you're in the highlands region it can get pretty darn cold in WV. By my maps, the mountains of WV are in zone 5a-b. That's not Minnesota cold, but at least as cold as most of Michigan, the southern tier of New York, most of Massachusetts, and coastal Maine. That said, the advice is still right on, and being a little overcautious never hurt anyone. Also, if you're at all like my in-laws who live in remote central WV, it's not at all common to lose power for days, even up to a week several times a year. Probably not a good idea to count on a heat lamp in that kind of territory. Heck, I don't think that my grandfather in-law had electric at his place until the mid 1970s.
