By the late 1950s, the family had moved to a larger house in San Dimas, California, where Snyder would spend the remainder of his childhood.
In January 1994, following his brother's death in a December 1993 plane crash, Snyder became president of In-N-Out Burger.
On Valentine's Day, 1981, Snyder married Lynda Lou Perkins (née Wilson), a divorcée from Torrance, California.
On December 3, 1999, Snyder died of congestive heart failure as a result of an accidental overdose of prescription painkillers.
At the time of his death, he had been living in a motorhome parked outside the Lancaster, California home of his first wife's nephew.
