If you store your cast iron in the oven? Because you live in the South and uae a convection toaster oven because IT'S HOT and you don't want to heat up the house?
Then, if you put a cantaloupe in the big oven so that the fruit flies don't find it, and then you forget about said cantaloupe, your cast iron will RUST. Rust. All of it ;( This part I didn't get; I mean, there's the moisture thing and all that but I'm a little offended that the cast iron got all pissy in...what? A week? Ten days? CHILL, boys, just chill a little. IT"S HOT.
And the cantaloupe will get all Stephen King on you.
