This picture is from the 1984 Frontier 500. I know because that is me pushing us out of the silt at the back of Willie's truck in the helmet.
Jack was a gentleman. I was writing for off road papers back then and he was the nicest guy, always a good story. And when he didn't have much to say I would go talk to his Mom, who would always know the rest of the story.I was so pumped when jack johnson started racing cars/truck ! big ups to m.s. concrete and Charlie Brown racing,,
