cots in the Astrodome
Hurricane Katrina has prompted people across the country to offer help, from the practical to the spiritual.

Volunteers set up cots on the floor of Houston's Astrodome early Thursday. More than 20,000 evacuees from Hurricane Katrina were expected to be transported from the New Orleans Superdome to the Astrodome over the next two days.
