Book in the Woods

Over in the Forest, Come Take a Peek by Marianne Berkes

Come for a self-guided, half-mile walk and read a story as you go. Learn the ways of forest animals, count the babies and search for hidden animals. Come and pounce like a fox, leap like a squirrel or scratch like a turkey. A perfect family nature adventure and a great way to get your kids out into the woods.
