One finds a fairly diverse collection of characters hanging around the Crossroads Mall Chess Club, (which I sometimes inaccurately refer to as the “Overlake Mall Chess Club”). Mostly it’s men who love chess, or are retired or otherwise have too much time on their hands. In my case, it’s a love of watching others play chess. And one meets people there and one gets to know them. And they find out about one’s other hobbies, in my case physics, and they talk about their own.
In the case of Forrest LeDuc, his other hobby is divination. His regular employment is in the gold fields of north Idaho. Divination has undoubtedly been a central part of mining since before man knew how to smelt metals. I suppose that Neanderthals used divination to find flints, as well as game, other tribes, etc. Divination (or dowsing) is not taught in mining engineering, but the students, at least when I was a student 30 years ago, are exposed to divination by the miners, when they work summers in the mines. Despite centuries of suppression by the combined forces of the church and science, divining or dowsing is still in use. See the recent Mother Earth News article for a description.
