Virginia Hollis is one of the girls missing from Camp Mystic, according to a social media post from Bregman. She was staying in Cabin Twins 2 when floodwaters from the Guadalupe rushed through the campgrounds. Ellen is a missing Camp Mystic camper, according to her family.

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.

When tragedies are in the news — natural disasters, plane crashes, fires — parents naturally and unavoidably react by thinking about what might happen to their own children. And children worry in turn about what might happen to them.
