Question of the Week: What can people do in their community to celebrate Earth Day?

Each week we ask a question related to the environment. Please let us know your thoughts as comments. Feel free to respond to earlier comments or post new ideas. Previous questions.

Earth Day, April 22, is next month.  Lots of communities hold events, block parties, and cleanups to encourage everyone to get involved, and have fun while they help protect the environment. Tell us about what folks in your community are thinking of doing.
