I suspect the wander-lust is driven from a story that comes out of his childhood. I'm sure I am screwing up some factual detail but as I recall there was one family vacation, no pee stops, 6 kids crammed in the backseat of something like a Studebaker.
My dad is the Trip Master.
This is no small group of kids we got going on...
Not one of them is a wallflower either!
(And this isn't even everybody)
