I have a gas oven...Do you think I could put them in there for a few minutes at a time on the lowest setting (not in the styrofoam bator, of course). It would take constant monitoring and wouldn't give you a stable temp, but at least they wouldn't get completely cold.
Or maybe use one of those heating pads that you can boil in water and just alternate between them.
If there's an ice storm, going to motel 6 is definitely out of the question for me. I live 15 minutes from town with huge hills on either side of me. I think the neighbors across the street have an generator, though.
How much do they cost? Forget running the fridge...I'll just stick everything outside. haha.
