Comparative Walls

There is some concern about the height of the proposed border wall between the US and Mexico.  It will be around 30 ft , though that will vary with terrain.  It will intimidate some folks who try to scale it.  Nancy Pelosi, a minority leader in the US, thought that was not the American way.  She may be right in that.  I did a quick comparison with another wall that is 20-23 feet high.  Not quite as intimidating but quite a bit wider.  That wall was the Great Wall of China which is 5,500 miles long.  That is about twice the length of the border.
