wild west had concrete blocks?
This is an interesting thought, which I had to look up...
The American Frontier (i.e. the old west) was a period that lasted from the late 1600s to 1912. The Concrete Masonry Unit can be traced back to the origin of Portland cement in 1872
So, it looks like there was some overlap, albeit, not very much...
