Back in 1976 when John Heston and Benett Kessler started Eastern Sierra News Service, a drought hit the Eastern Sierra and so did major political controversy over the Department of Water and Power’s aggressive groundwater pumping. It was the fall of that year when two young, local men bombed the Alabama Gates, part of the LA Aqueduct.
