Roger Ogden posted a video on YouTube of prototypes of the border wall. Ogden writes:
I was able to slip up on the compound where they are building Trump’s border wall prototypes in Otay Mesa, near San Diego. I call it “Fort Apache” due to the high security, isolation and the wall around it, not to mention mounted Border Patrol guarding the area. I snuck a little video with my phone before I felt like I might be discovered and had to leave. Sorry about the poor quality of the video.
