My dad is still alive and got me into motorcycles (and British sports cars). But somehow we never rode together when I was young and when I got bike in riding 8 years ago it was because he couldn't ride any more due to his Parkinson's and so I bought his bike from him.
I'm sorry you didn't get to ride with your dad. As we all know, it's impossible to describe to a non-rider exactly what the experience is like and why we love it so much. You have to do it to understand. I explained that to my son long ago. When we finally got to ride on Sunday, I mentioned to it to him afterwards and he agreed that there's no true way to describe the experience and the thrill.
Great quote from The Outlaw Josey Wales, by the way - one of my favorites. I thought Chief Dan George nearly stole the show.
