In March 2009, I went to Andhra Pradesh, India, on a volunteer project with an NGO called Longitude. We went to a village called Gummallapadu to help widows' families and other Dalit people, or members of the caste formerly known as "untouchables." We had an amazing experience. If you're interested in more about the program or about volunteering in India or elsewhere, I'd love to talk to you. Check out the project's Building Communities blog, too!
