Let’s Go Outdoors, which connects city communities to outdoor experiences, offers this event for people of all ages at three park locations: Houston Meadow, Saylor Grove, and Blue Bell Park. Participants will learn to use a handheld GPS device to look for caches (hidden containers) that hold tickets to turn in for prizes. The event starts at Valley Green. Masks and social distancing required. Register at http://www.letsgooutdoors.net/trash-or-cache--beginner-geocaching-.html.
