Do a little investigative reporting of your own. Go online and search for a public interest group in your community. Identify its officers, objectives, sources and amount of financial support, and size and characteristics of membership. List some examples of its recent actions and/or accomplishments. You should be able to choose from environmental groups, animal protection groups, political action committees, and so on. Visit the website of the local chamber of commerce, the Better Business Bureau, or local government agencies for help.
