An authentic narrow-gauge railroad which circled the grounds provided entertainment for hundreds of children who thronged Gold Creek Park during its popular 1960s years. In the locomotive cab was William G. Tyrrell, pet food manufacturer, who created the park for family entertainment. The 74-acre site also had a log fort, pioneer grist mill, four swimming pools, picnic areas and an ice-skating dome. The Woodinville Heritage Society will highlight the park in its prime years during a program Saturday, May 17, at 10 a.m. The event will be at the Sammamish Valley Grange on 140th Avenue NE, just north of the Old Hollywood Schoolhouse. The PowerPoint program includes numerous rare photos and comments from former Park employees who will be present.
