Leaders of a Georgia nonprofit that builds and repairs homes say four volunteers were hurt in a van crash near burley as they traveled across the country on a fund-raising trip.  Chris Johnson, a spokesman for the Americus-based Fuller Center for Housing, says the injured people were among eight volunteer cyclists who were riding in a van when it crashed Tuesday night. Johnson says the vehicle landed on its roof. The injured volunteers -- three from Georgia and one from Colorado -- were taken by ambulance to a hospital, where they were treated and released. Johnson says the volunteers are cyclists pedaling a 3,600-mile route from Seattle to Washington, D.C., to raise money for the Fuller Center. The injured Georgia cyclists are from Athens and Savannah.
