Barter economy

(1992)
My Aunt Lois gave me a $10 gold pen in a case and on chain around my neck, and I gave it for my first ride in a plane for 10 minutes.  Maybe it was $5 for five minutes - whatever.  Lorin watched me, would not go up, and said he was glad I was safe on ground again, but I wished for a longer ride.  That was at the football field, I think.
