Did you know that the second Sunday of September is International Rock Flipping Day? We’re celebrating a few days late with a walk through the conservation land to flip some rocks and explore the tiny and mysterious worlds underneath! Visit the IRFD website to take a look at what others have discovered and post your own photos: Please note that the conservation land trails are not ADA or stroller accessible;  please wear appropriate footwear and clothing.
