One summer afternoon in the small town of Coulterville, Ill., a young James Hayes sat outside beside his father, James Hayes Sr., in a tree-filled portion of the family’s ranch that the Hayes’ referred to as “the park.” The pair sat atop the front of a bulldozer parked amidst the greenery, with the front engine compartment open as Hayes Sr. worked on the complex machinery within. Hayes and his brother, Ricardo Hayes, regularly helped their father with his mechanic work, handing him the tools he needed while observing all the details of whatever he brought in to work on.
