Upcoming Meetings

Saturday, May 16, 2015 - PhACT Expedition to the Mullica River

Time: 10:00 AM
Location: On site Details
James F. McCloy and Ray Miller, Jr in Phantom of the Pines (1998) wrote that in 1928 not far from Batsto "William Bozarth encounters the Jersey Devil along the Mullica River". And in 1936 at Batsto he "sees the Jersey Devil again." Henry Charlton Beck in Jersey Geneses: The Story of the Mullica River (1945) had noted that the obituary for Fire Warden Bozarth stated that he "was the last man known to have seen The Jersey Devil."

Our guide, Don Nigroni, will trace two folkloric traditions concerning the Jersey Devil, namely, the witch tradition, dating back to at least 1859, and the curse tradition, from at least 1887, to the present day. Accompanying the expedition will be Robb Kerr and Jeff Cooney, who will be providing zoological and botanical information about the Pine Barrens, and professional photographer Ned Levi, who will be photo-documenting the day's activities. We will meet at the Visitor Center at Historic Batsto Village ( at 10:00 AM. After walking through the village, where scenes for 13th Child: Legend of the Jersey Devil (2002) were filmed, we will hike the Tom's Pond Trail (1.8 miles) which proceeds over the Mullica River. After lunch, participants can take a self-guided tour of Batsto Village.

Although we may not find any monsters, we will learn about the history of the bog iron era in the 18th and 19th centuries in the Pine Barrens and see pink lady's slippers and carnivorous plants like sundews and pitcher plants. Bring insect repellent, sturdy shoes, lunch, and a camera. The event is free and open to the public.

Saturday, July 18, 2015 - PhACT Picnic

Time: 10:00 AM to 2:00 PM
Location: Mondauk Common Park, Upper Dublin Details
We always have fun visiting, eating, and playing sports. Bring your own food; you can cook on the grill. And bring stuff to throw. We have reserved the pavilion in the woods on the Southeast corner of Mondauk Common park in Upper Dublin. This is good fun for the whole family. We have negotiated with the park ants and they agree to not show up before 1:00 PM.

We will again have a book swap - it can be a great free way to build up a science/skeptic book collection - or help someone else do so.

Saturday, September 19, 2015 - Einstein's Dice and Schrödinger's Cat

Time: 2:00 PM
Location: To Be Determined Details
Speaker: Paul Halpern
