Search the Pennypack pond and stream for frogs’ eggs, tadpoles, frogs, turtles, dragonfly nymphs, salamanders, and other critters that come out in the warmth of May.  Fun for all ages, but children must be accompanied by an adult.  Wear clothes to get wet and muddy such as old sneakers, mud boots, or even waders.  Bring nets and buckets if you have them.  Pre-registration required by June 6.
