Feel free, however, to stand a few feet away from the border with them.
The enormity of the vital task entrusted to (perhaps foisted upon would be more descriptive) an inadequate number of Border Patrol agents is not truly apparent until you’re standing on the border. I thanked all of the agents I encountered today. Without exception, every agent was very polite and professional.
The “big fence” becomes a series of welded-together “vehicle barriers”, which gives way to a simple barbed wire fence a few miles later. This is what separates the United States from Mexico. This photo was taken at the border, looking towards the east, from 31.450788,-111.44285 (Lat/long provided for easy Google Maps reference).
