Use the PGC Grain Silos (see Map Pin below) on County Rd D-E as a landmark for the park entrance. Take County Rd 18 and turn onto County Rd D-E which is also marked Dame St. The Pettisville Park Entrance is just west of the PGC Grain Silos. Click for popUp of local view. Please Note- Google Maps has shown some confusing information about Pettisvile. Their map pin is accurate for the Park, but sometimes they use a Wauseon mailing address for the Pettisville Park. The Park Entrance is on County Rd D-E.
