Hundreds of volunteers show up each day to help out in tornado-ravaged Moore and Oklahoma City.
They come from all across the country, many saying they had foregone their usual mission trips to instead pitch in and help the residents dig out of the massive tornadoes.
Volunteers are urged to check with church and civic organizations rather than coming to town and just showing up in the tornado zone.
People who need help, or want to help, can visit the Serve Moore website.
