I was amazed to see the articles in the news about the border fence debacle, where construction evidently went full-tilt along the US-Mexico border to construct a fence to prevent illegal immigration, following 120-year-old barbed wire strands, and without any apparent proper surveying research, and construction stakeout.
Evidently there are legal monuments spaced along the border, tall metal or concrete markers managed by the International Boundary and Water Commission, jointly operated by the US and Mexican government, but in constructing the fence, they evidently failed to do their due dilligence, and in fact the fence was revealed to be encroaching into Mexican territory. Certainly historic fence lines can have some meaning and significance as boundary evidence and as lines of possession in certain circumstances, but in this circumstance, particularly where an international boundary is concerned, I am frankly disturbed that proper survey work went by the wayside.
Look at the 'organization' building it. Why should we expect anything different?
