I have my grandmothers (or great's, not sure) either way I love it. I only season it occasionally and it's great. I do prefer my scrambled eggs in nonstick pan but that's also becuase of my DH too! I don't think he believes me about the soap and he thinks its gross that I wouldn't use soap on it.
I might sound loony but I feel like its healthier to cook with cast iron (supposedly helps with low iron levels) than nonstick pans (which is just some strange chemicals). My family is southern, but I never thought this was "a southern" thing...
Heres a good one
