The photo of the illegals going over the wall was taken close to Boulevard, California. I also spent some time on the ground close to Naco and also did a fly-over Naco in a Cessna 150. There is a lot of remote border with no hint of a fence in that area. Luckily there are a LOT of civilians working beside Border Patrol to stop the groups. Of course BP will probably deny it publicly due to political pressure from DC, but the BP agents I talked with, off the record, really appreciates these civilians.
BTW: AZTOY, thanks for your service and stay safe over there.
