I moved across the Potomac River from Virginia a few years ago and now call Maryland "home".
Glen Echo Park, Glen Echo, MD. From their web site: "Formerly a popular amusement park, today the Park is home to a community of artists, educators, dancers, and performers who share their knowledge and expertise with more than 400,000 people each year." Open weekends. The park's beautiful carousel is still in operation. Annual art show held on Labor Day weekend.
