Black widows are common too but they don't usually come inside inhabited places. I think it is a sound issue or they don't like the electronic fields that a house flowing with current throws off. The places I find them in are always quiet an undisturbed.

I have been know to make day trips to the mountains just to eat there. I think I saw one in Knoxville years ago. I have been married for 7 years and have not made those trips since..... :/
