It must have taken hundreds of hours to build the walls and they often stretched over long distances.
However, materials were free and there may have been plenty of time without t.v., computers, iPads and other modern distractions.
The stone walls seen in this post are at the top of Mt. Greylock in Western Massachusetts.
They are nice to look at as well as sit on!
DO YOU HAVE STONE WALLS ON YOUR PROPERTY?
