Join us at 10 AM on July 19 and encounter the wonders of nature at Big Rock Park. Discover the plants and trees and learn what animals they might be hiding.  Listen for the sounds of life and observe how the environment changes with the seasons.  This walk is open to children, ages 5 to 12, and their families, and will be led by Nature Vision, a nonprofit organization dedicated to fostering appreciation and stewardship of our environment.  It will last for approximately one hour and cover just under a mile.  Meet at the entrance to Big Rock Park on SE 8^th Street.
