All ages are invited to join Narrow River Preservation Association for a hands-on exploration of fish, shellfish, crabs and other inhabitants of the Narrow (Pettaquamscutt) River. Participants will use nets large and small to catch river creatures and examine them in touch tanks and under microscopes. Experts and guidebooks will be on hand. This event is free, and children under 12 must be accompanied by an adult. Participants are welcome to get into the water, so dress appropriately. Because this is a natural environment, there are sharp objects in the water. Boots, sandals or shoes that can get wet are recommended. The gathering area is a field with grass and dirt surfaces. Wheelchairs are welcome.
