Two days before flash floods on the Guadalupe River in Texas killed dozens of campers at a Christian girls summer camp, a state inspector approved operations, noting there was a written plan for responding to natural disasters.

Brooklyn and Bailey McKnight's little sister, Paisley, was at a camp on a smaller arm of the Guadalupe River. The 14-year-old was "just miles" away from Camp Mystic in Central Texas, which has been devastated by the deadly floodwaters spurred by extreme rainfall on July 4.

At least 27 died in one of the worst disasters ever for summer camps. The tragedy shines a spotlight on America's camps and whether they're safe.
