I don't know what you are trying to convey with this picture but from
what I can see the Mexican side looks like the better side. It is built
up with what looks like good infrastructure. Maybe tourism is big
business there. If the American planers who drew up this arbitrary
border wanted to keep Mexicans out then they made a big mistake.
Borders, to be well defined, should include naturals barriers such as
rivers, mountains, deserts, etc.
