I wouldn't be involved with O-gauge and tinplate if it wasn't for the affordable "junk" that I can repair to build fun operable vintage trains. Sunday afternoons are bargain time. Occasionally, vendors just leave their unsold stuff behind with a "FREE" sign. Don't knock it !
But I haven't been to a train show since 2019 because of Covid, and am wary of the future. I honestly don't need any more train stuff at this point, anyhow. I have a backlog of parts and projects.
