In September of 1947 John Gunderson founded a Hot Rod Club.
He called it The Trompers of Eagle Rock
John had his sister Jean handpaint the first plaques on polished and shaped fiberboard. As Jean finished up her task, John called up the other 6 founding members; have them come over to his house where they would affix the freshly painted plaques to the back of their roadsters. That made it official. They were a member of the Trompers, and were now ready to go to the lakes.
