From the MACPS site:
Founded in January 2017, MACPS is a not-for-profit organization dedicated to promoting scientific knowledge, education, and general awareness of carnivorous plants and their cultivation. We hold four meetings a year throughout PA, MD, VA, WV, DE, NJ, NY, and Washington, D.C., and also go on field trips and exchange cultivation advice that is uniquely suited for this region.
Our meetings are open to everyone! They feature lunch, a moderated Q&A on carnivorous plant cultivation, talks, workshops, and a plant auction. You are always encouraged to bring plants to display and auction.
