Cindy Manley was a summer camp counselor in 1987 when a different devastating flood scarred the Texas Hill Country. The Heart O’ the Hills camp is on the Guadalupe River, where a massive search continues for more than 160 people who are believed to still be missing after catastrophic flooding over the July Fourth holiday. Decades earlier, Manley said there was an informal system in place when the river started rising: camps upstream would call down a warning and then get kids out of their bunks and to higher ground.
