This is an interesting and valuable thread (fall trades from rust-free gardens), but sadly, not all of us are rust free.
I would suggest a trade (or send-for-postage) from the rusty gardens, but I am sure that would be upsetting to some (state Ag departments included), even if the giver was upright and honest about his garden/plant status, and the recipient didn't care (because they are already in the Rust Bucket or have cold winters).
