About ten years ago, I had a beautiful 1941 Plymouth PT25 pickup. A bit of a hot rod! Lots of Offy and Clifford spied parts on the 1958 Plymouth flattie.
I had it at a show, and a young family came up to look at it. The kids, 5 and 8, wanted to see the interior. Dad said "don't touch!" and they minded well. I was right there and asked the kids if they'd like to see inside and sit in it. They were all over that idea, so with Dad's permission, I opened the door and said "get in!"...they both dug that a lit! Mom took pics of them in the truck. Dad thanked me for meeting them sit in it, and two kids got to appreciate a truck older than their grandparents. It was fun, and it didn't hurt anyone or anything to do that. Do I do that at every show? No. Gotta be in the right mood, and whoever asks, has to have a functioning brain.
