When I was Motorcycle Mechanics Institute's content creator many years ago, I was tasked with updating and qualifying much of the school's material. In this endeavor I benefitted from access to some really talented people, "subject matter experts", creatives call them. One of them still lingers in my memory, more than twenty years later. He knew more about vintage Harley-Davidsons than anyone I have ever read or talked with or worked with, and even then I was convinced he was an older version of myself, a career mechanic who had lived what he knew and really knew what he knew. And I remember him because, like me now, he was old, vastly experienced, and came close to pleading with me to consider the expert techniques he was explaining, techniques that were not those published in books and not those accepted by the majority. What an awesome meeting. I miss that fella. As I think back I realize, that in exploring his unappreciated, earnest expertise, I was previewing my later self.
