Here is a suggestion sent to me if there is any interest we will join them.
Do you and your members have any interest in having a joint photography workshop with my group, the Manhattan Figure Study & Lighting Workshop http://photo.meetup.c..
During the summer we occasionally meet in PA (near the water gap) for a figure photography session with a waterfall as the background. We usually meet for early lunch & then we shoot until dinner time. Since we hire a model, there is cost involved, but it's worth it. We always shoot on a weekday, usually a Monday, Tuesday or Wed.
Please let me know if there is any interest from your Dowingtown folks.
