Latino children from Montgomery County, Maryland helped paint a mural Saturday as part of a mentoring project while celebrating racial integration in Glen Echo Park. (WTOP/Dick Uliano) There’s a new mural in Glen Echo Park in Montgomery County, Maryland that celebrates both the 100th anniversary of a famous carousel and a protest that led to the amusement park’s eventual integration. But the piece wasn’t painted by just anyone; it was painted by teenagers served by a Gaithersburg, Maryland nonprofit called Identity Inc. The project was born through a partnership with an Annapolis nonprofit that connects at-risk kids with artists who teach them how to make murals.
