It does look interesting! Finding it might take some googling around. In one quick search, I found this 2004 article inThe New York Times https://www.nytimes.com/2004/08/03/science/side-effects-sociology-history-where-to-put-the-blanket.html, which cited several earlier studies. The closest one I saw was “In 1981 Dr. Herman W. Smith, now retired from the University of Missouri at St. Louis, published a paper called, ''Territorial Spacing on a Beach Revisited: A Cross-National Exploration,'' in Social Psychology Quarterly.” If that’s not the one referenced, you might look at his citations, or knock around in that journal’s index and wider indexes of social psych.
