Join Marin County Parks for a day of discovery and play! We’re leaving the projector and Power Point at the office and hitting the road. Come learn about upcoming projects and let us know what you think about your neighborhood park. There will be a scavenger hunt, nature walk, snacks, refreshments, and last but not least, Earth Day festivities. Location: Hal Brown Park at Creekside on Bon Air Road (across from Marin General Hospital).
