Edwin Fisher repairs a damaged geocache at August A. Busch Wildlife Area in St. Charles, Mo. on April 5, 2020. “Geocaching is a great way for families to get outdoors and be active,” Fisher said. “It is like a scavenger hunt, but using a GPS with a set of coordinates,” With the closures of parks on April 3, 2020, many residents have been pushed to continue their outdoor activities at conservation areas or parks that remain open outside of the St. Louis County Area.
