A decade ago, our dear FReeper Libertina was with me in a car being driven by an old railroad man who had gotten out of the game and taken over his father-in-law's business which he turned into a multi-million dollar success.
He said, "Back then, we were running reefers out of Spokane."
Libertina screamed, "You were doing what?!!!!"
I had to educate her as to the railroad meaning of the word.
