Second Sunday with Friends
May 10, 2026, 1:30 – 3pm
Have you ever wondered about things as you walked through the woods? Do woodpeckers ever get headaches? How do turtles breathe under water? Why do leaves turn colors in the fall and not just fall off? If you have ever wondered about these things, join volunteer Judi DiMaio and find out!

Registration is required at ttsu.me/answers. In-person will be held at the Helen C. Fenske Visitor Center, 32 Pleasant Plains Road, Harding Township, NJ 07920. The Zoom logon will be emailed to all registrants on Sunday, May 10 at Noon.
