Friendship Park resides in the middle of Border Field State Park. To get there, you must drive, or usually walk because the area is prone to flooding with the least bit of rain. From the entrance of the park, you go towards the border where you’ll see not only one, but two walls.
The first was erected in 1994 during the Clinton Administration’s Operation Gatekeeper. This wall is made of recycled military landing mat. (I’ve read two version of where this map came from: either WWII or Vietnam.)
The second wall was constructed in 2008-9 during the Bush Administration after a series of bills passed. The second wall was made of white concrete in some places. Here it’s a see-through fence.
Border activists have had spats over whether to term the border a “fence” or a “wall”. Personally, I’m not sure what the importance is. Both terms refer to barriers and the visual below is enough to give you a taste of what it means to live along the line.
Border Patrol will explain that the double fence is not constructed to keep people from climbing up the fence and crossing. The double fence is constructed to delay an individual from crossing, thereby allowing border patrol to get to the individual in time to apprehend them.
You can see the ecological displacement that was necessary in order to construct these walls (not to mention displacement and/or destruction of unexcavated Kumeyaay artefacts).
