Earth Day, Arbor Day events in the District, Maryland and Virginia
Clean air to breathe, cool water to drink, shady trees to relax under.
The Earth gives us so much and asks so little in return. Show some gratitude this weekend by attending one of the numerous cleanups, concerts and festivals around the area.
And Earth Day (which was officially yesterday) isn't the only reason to get outside and enjoy the world around you this weekend. Arbor Day is April 30, and National Park Week, which runs through Sunday.
During National Park Week entrance is free to all national parks, and many are having special celebrations to draw you outside. Visit http:/
