I didn't realize until he started talking, that this guy was one of the people involved with the publishing of the book Stretching, which I've used for years. If I had picked up on that fact, I would have brought my very used copy. He even had the Stretching software installed on his computer, which I have used in the past.
In Tiny Homes on the Move, we got a slide show of exactly that. Many people in the audience were tiny homes enthusiasts and so it was amusing when people asked specific questions about tiny home construction, only to hear the author himself wasn't a tiny home enthusiast himself.
I enjoyed that two people in the audience both wore hot pink and also sat near each other.
