"Jack McCall was a fixture at the local farmers market, where he sold avocados and other fruits he grew on his 20-acre ranch in Cambria, on California’s Central Coast.
The U.S. postal worker and Little League coach was “very environmentally friendly,” said Teri McCall, his wife of 41 years. He avoided chemicals, using only his tractor-mower to root out the thistle and other weeds that continually sprouted on the flat areas of the ranch.
But he did make one exception to that rule — a fateful one, his wife now believes. For more than three decades, on the hilly parts of the ranch where he grew the avocados, and around newly planted fruit trees, Jack donned a backpack sprayer and doused weeds with the widely sold herbicide Roundup."
