Camp Mystic has announced that it plans to reopen one of its Texas sites, where 27 girls and counselors died in a flood. The flooding that swept through Texas in July killed at least 136 people — including more than two dozen children and counselors at the century-old summer camp for girls that was among the first areas inundated. Located in a low-lying area along the Guadalupe River in a region known as flash flood alley, the camp was hit when historic floodwaters tore through its property before dawn on July 4.
