That is what led to the collapse of the old "ley line " thinking .The stats showed that finding lines on maps was what was to be expected by chance .The choice was immense and usually included churches ,(which were always built on ancient sites after all ,cough) ,the symbol of a church on the map also took up a fair amount of space much greaer than the actual church ,providing a graet target . Medieval Moats were a favourite ,there are so many in Norfolk and Suffolk you can't go wrong , hill forts ,cross roads , straight stretches of road ,the "round field" in TOSOLE takes a bit of beating .You didn't need ancient sites .
Try it , you'll find dozens with little effort .
The accuracy of the lines were often a joke too . Think of the St Michael line from "The View Over Atlantis "
Most "hunters " got the point and went off into other areas . Then it became "energies " .The yhad learnt the lesson , can't refute what you can't see or measure .
