In 1888, my great-great-great grandfather, Daniel Light Kline opened Valley Glen Park. This popular park and boating area in Palmyra, Pennsylvania attracted hundreds of people each summer with its water slides and other attractions. It was at Valley Glen Park where Milton S. Hershey would bring his workers for leisurely outings and relaxation. On one such occasion, Kline suggested, “Milton, why don’t you start a park on your hilly country where nothing can grow?” Hershey took that advice and built what is now America’s “sweetest” amusement park.
Little did Milton know that he would, in a way, return the favor. 78 years later, Daniel’s great-grandson, Gerald Kline, and Gerald’s wife, Linda, would be lost in a tragic drunk driving accident. Their orphaned sons, Jerry and Paul, would spend their childhood at the Milton Hershey School for Boys.
