Ok, my own dad wouldn't be caught dead on 2 wheels, but HIS dad didn't have a problem with the idea. This is a photo of yours truly (in brown) riding around the back yard with my grandfather in 1975 on his Honda 450. I was 4. He was in his mid 50's at the time. Below is a picture of my own bike photographed in the same general area of the yard 43 years later in 2018. If you wonder what ever happened to the Honda, it still exists in a slightly different look and I actually rode it up the road a few weeks ago.
