It was the spring of 1980, mid to late May, by Karle’s recollection. Make it a Tuesday. Karle, a construction worker and later a contractor, had just gotten home from work. His older brother, George Karle Jr., was a fine carpenter too, but, Tom Karle says, less interested in work than in what he could find with his boat, fishing and diving in the bay. So on this particular sunny day, with his truck parked halfway up Tom Karle’s lawn, George Karle Jr. says, “I want two of those chokers,” meaning half-inch steel cable devices, 10 feet long, used for hoisting and hauling things like engine blocks, telephone poles, and steel I-beams.
