The possible closing of the Greenville (SC) Shriners Hospital for Children has mobilized the community, with calls for fundraisers, letter-writing campaigns, and a Facebook page dedicated to keeping the facility open. Ralph Semb, chief executive officer of the hospital, said he's impressed so many people want to help, but added cuts must be made one way or another because the organization can't continue drawing down its endowment to make up for a budget shortfall.
