Bring the whole family to the historic Wagner Ranch Nature Area for a free festival in honor of Earth Day. The event features Native American singers and drummers, nature crafts and games, frontier chemistry, docent tours through the ranch property, food, music, and the chance to test drive an electric BMWi3. The 134-year-old ranch serves as an outdoor classroom and is open to the public only two days per year, so enjoy the chance to visit this treasured venue. www.fwrna.org
