Book excerpt: When Don Snyder was teaching the game of golf to his son, Jack, they made a pact: if Jack ever played on a pro golf tour, Don would walk beside him as his caddie. So when Jack developed into a standout college golfer years later, Don left the comfort of his Maine home and moved to St. Andrews, Scotland, to learn from the best caddies in the world on famed courses like the Old Course and Kingsbarns. He eventually fought his way onto the full-time caddie rotation and recorded the fascinating stories of golfers from every station in life. A world away, Jack endured his own arduous trials, rising through the ranks and battling within the college golf system. When Don and Jack finally reunite to face the challenges of high-level golf competition together, this moving, one-of-a-kind narrative reveals the special bond between father and son.
