For those of you who haven't seen it

 

This is what the border fence looks like.

 

From the U.S. side.

 

From the Mexico side.

 

Here in Texas, the border fence isn’t exactly on the border.  The river is the border.  We can’t really put a fence right down the middle of the Rio Grande, so the fence location is a compromise.  Since the Mexican government hasn’t actually volunteered to build it or pay for it, the fence is located on U.S. soil and follows a path that approximates our border, but is practical to build on.  It leaves a lot of land on the other side.

 

The fence is not continuous.  There are gaps.  The Border Patrol does what they can to monitor the gaps.  It’s not unusual for us to walk and bird along the border fence.  It’s not unusual for us to walk or drive through gaps in the fence and bird on the other side.  These pictures are from near the town of Hidalgo.

 

One birding park we go to, Sable Palm Sanctuary, is entirely on the other side of the border fence.

Trace the park road north to the next road up.  I put a pin there.  Zoom in.  That’s the border fence.  All the farms, fields, and birding spots between there and the river are cut off from the rest of the U.S. except for a few gaps in the fence.
