Thursday, Aug. 20: Beachcombing with John Galluzzo: There’s an art to beachcombing, and we’ll dabble in it. We’ll find what strikes our fancy and ask fanciful questions – where did it come from, and in whose hands was it last? Along the way, we’ll help clean the beach.

Tuesday, Aug. 25: Winging it! Birding with John Galluzzo. Sometimes we just gotta do what we do best. Birding! NOTE: Pre-registration is required as this program is limited to 10 participants.

Thursday, Aug. 27: Wrap-Up, Trivia and one last Birding Run! We’ll take one last trip along the beach and revisit the past two, glorious summer months. NOTE: Pre-registration is required as this program is limited to 10 participants.
