While serenely sailing the York River, we got to talking with Carla and Claude Davis of Atlantic City about Superstorm Sandy and how it devastated northern New Jersey in 2012. People can go for days without electricity, but not water. “They take water for granted,” Carla said. Claude works in the city water department. “You can always light a candle, but that won’t provide you water,” he said. People can also live without TV, but not their smart phones. I allowed as how I would hate to live away from the river. “Well then, you need water for sustainability on two levels,” Claude said.
