I found another Berner group that meets the first Sunday of every month in PA. Looks like a great place. According to my Gps its only an hour from Berlin.
"DIRECTIONS: Pawling Farm Parking:
After crossing the bridge on Pawlings Road, you will see a sign similar to the one above for River Trail parking. Pass that one by as that lot is smaller. Continue on until you see the sign above for Pawling Farm on the right. Parking is clearly marked with signs just past Pawling Barn, across from the kiosk.
