Join the crew of the Acasta as they demonstrate map making techniques while charting the South River. Afloat and ashore, these sailors will be charting the waters just off our shore and you are invited to chip in. Included with general admission. Free for members.

Electric Vehicles are here! We're closing down Historic Maryland Avenue to traffic on Sunday so you can come and and learn how EVs work, what they cost, and more. Talk to owners, people who have been driving electric for years, who can tell you all about their experiences. Talk to dealers about purchasing and leasing. And, we're going to feature a Chevy Bolt, a marked patrol car that the Hyattsville Police Department will bring! Are you curious about driving electric? You know you are. Come and get your questions answered.
