Gaithersburg Community Museum, 9 S. Summit Avenue, Gaithersburg, MD 20877.
Explore Gaithersburg with the first Gaithersburg Scavenger Hunt. Pick up your instruction card and then go look for clues. Visitors can enjoy art in the making while local plein air artists capture the historic landscape in and around the Rail Complex in Olde Towne. We will be celebrating the fun of playing games - old-fashioned games and then, with a modern twist, the Imagination Playground blue building blocks. The Martin Family String Band will be performing at 2:30. As always, play and learn in the Museum’s hands-on learning centers and, possibly, see a REAL train go by on the active CSX tracks next to the museum.

International Latitude Observatory, Observatory Park, 100 DeSellum Avenue, Gaithersburg, MD 20877.
