How/where will you search?
Wondering if David somehow got on a bus for Montreal or the NY Catskills, where there is a large O.J. community?
Any chance that Mr Mines wanted to leave his religious life behind ?
imo, speculation.
History of Borscht Belt Hotels and Bungalow Colonies in the Catskills
"As geography, the Catskills are a mountainous region of southeastern New York State. As synecdoche, they are a now-vanished way of life. For your parents and grandparents, the Catskills from the 1920s through the 1970s was the Borscht Belt, the Jewish Alps, “Solomon” County, the summer place to be if you were Jewish.
A blurb on the home page of the Catskills Institute says it well: “New Yorkers hungry for mountain air, good food, and the American way of leisure came to the mountains by the thousands, and by the 1950s, more than a million people inhabited the summer world of bungalow colonies, summer camps, and small hotels"
