A good social justice opportunity is available in St. Louis. The position comes with room & board, health insurance, and monthly stipend and lasts 10.5 months. You'd be working with a friend of mine who works on health reform, economic justice, environment, and TCH projects. She'd be a great mentor and is extremely involved in these issues at the city, state, and federal level. You can find out more about the position here: http://www.lorettovolunteers.org/
If interested I can put you in touch with her or try to get answers to any questions.
