Brian. I'm 70 years old, and I ask dumb questions quite often. I asked the Docent so many questions, when he took me for a drive in a Model T at Ford's Greenfield Village, that he was probably happy to end my tour. My grandsons think I'm a genius with tools of any sort, but a bit of an idiot with phones and computers!
I do have to compliment you on giving people the experience of riding in your old cars. I get lots of questions when I am at car shows with my '46 Coupe, and I answer them all with great patience. I also let people sit in my car (no ice cream!), and will often start the engine, just so they can hear a flathead run. People are curious, and they learn by asking questions or being shown.
I particularly enjoy talking to people from the generation before mine. They tell stories about the first car they bought after the war, how they used to cut them up to race with, and how comfortable and spacious the back seat was on a date!
Gotta love old cars and old peoples memories.
