The Wall - Us Mexico Interactive Border Map
Here is a map of the US / Mexico border. It's from a series of articles written by the Arizona Republic and USA Today on the wal American Emperor Trump wants to build between the Mexican border and America.
Most of it is unfenced and you can walk across it.
Many of the fences are only designed to stop cars and you can walk thru them, under them or around them.
My view on the border is we should rip down all the fences between Mexico and Canada and let anybody into the USA that wants to come into the USA. We should also fire everybody in the INS, ICE, Border Patrol, US Customs and Immigration or La Migra as I call them.
