Earth Day events in the Washington, DC, region

Earth Day is April 22, less than two weeks from now. Earth Day events will take place throughout the month, often on the weekends. I did some quick Web surfing and found these local events:

• Earth Day on the National Mall: Yes, there will be a big event and a concert downtown. It will happen Sunday, April 19. The Earth Day Network and Green Apple Festival are teaming up to produce it. No exact schedule is available yet, nor is a list of bands. I'll try to get the info ASAP. Meanwhile, check out Earth Day on the National Mall and from Planet Green, the Volunteer Central page, where you can find Earth Day volunteer opportunities in conjunction with the festival and concert.
• Anacostia River Cleanup and Celebration: Takes place April 18 at 30 sites in D.C., Prince George's County and Montgomery County. Organized by the Anacostia Watershed Society.
