The DC area has tons of great places to take pictures! Here are some of my favorites:
The Franciscan Monastery, Brookland, DC - This location requires a bit of planning because you must request permission for us to shoot there.
Lincoln Park, Capitol Hill - Playground!
Meridian Park, Columbia Heights - Steps and interesting architecture.
Mitchell Park, Dupont Circle - Playground!
National Arboretum - Lovely tree-lined walks.
Stanton Park, Capitol Hill - Playground!
