I have a nice collection of cast iron in the basement, including a wonderful chicken fryer, which is about 6" deep and has a lid. It's dry down there, so nothing is rusty, but it's filthy.
I can't use the stuff because it's just too darned heavy for me anymore, and I suppose I could clean it up and sell it, but I prefer to hang on to it, just in case we should ever have an emergency where we have to cook over an open fire. You just never know.
We get by with a little help from our friends
