I'm not watching a 1hr presentation/video. Your quoted math is nonsense. There's ~250k miles of stone wall in New England. Divide by a ~100yr construction period, and you get 2500mi/yr. Average pop was say 1.25mil (I'm underestimating for easy math) over the period so you get 1.25mil person*years per year. The mathematical writing should be on the wall at this point. https://en.wikipedia.org/wiki/Demographics_of_New_England#Population https://en.wikipedia.org/wiki/Demographics_of_New_England#Po...
