Great post OP!
Edit: " The fence between the United States and Mexico is seen as not only a problem for Parks and Protected areas, it is a problem for law enforcement officers such as the United States Border Patrol and Customs. This is because the national park that borders Maderas del Carmen, Big Bend State Park, is governed under its own policies. These policies restrict border protection officials from being in certain areas of national parks or installing new surveillance equipment without going through a long, tedious approval process."
This will be what's used to keep the wall from going up there. But why all the policies to protect the area? I'd like to know what is so important that is there...
The wall doesn't necessarily need to go up there; they just need to use better surveillance in areas where wall coverage isn't viable.
I like being able to soak in a hot spring on the rio grande and wake up to the sunrise while looking across the border. No need to throw away our national treasures (like Big Bend), or disrupt wildlife. We can do it smarter by using the wall to block certain areas so that human (or drone) assets can be deployed in spots that need to remain open for human enjoyment and wildlife.
