In Bethany Louisiana, a natural gas leak forced about 30 families out of their homes. On Wednesday, officials ordered a mandatory evacuation for everyone living within a square mile of the gas leak. Most of them stayed at a nearby hotel, while others stayed at Camp Bethany or with family members. Around noon on Saturday, the evacuees were told it was safe to return home. Crews working the leak don't know what caused it, but say they do have the problem under control.
