People do speak highly of the Appalachia Volunteers program (bit.ly/BC-APPA), which other folks might not know also visits other areas as well, such as Detroit and New Orleans, to serve the poor and marginalized of the US. Helping people build and repair homes who might not otherwise be able to afford them must be gratifying work.
It must feel good to be helpful. A lot of people are obsessed with all the opportunities at the Volunteer and Service Learning Center, too: bit.ly/BCVSLC
