He is Irish to me, but half the world is Irish, myself included, so if you want to call him an American it's all right with me.
This proves me one thing: although he had a face I was sure to recognize anywhere, I didn't, here. I understand better why no one recognizes some of my world-famous Art and Cars people.
This other Irishman I identified, by the way, Kent McCord, I had never heard of him on the opposite. I just understood that "we live outdoors" (in your clue) must have been a tagline for a brand, and easily found Gander Mountain, then the guy. Pure googling.
By the way: I was wondering where your picture came from. "Hell Drivers" it is.
