I guess that’s why the buoys are still in the middle of the river, even though the Fed’s tried to stop it. The land between those two Port of Entry’s is privately owned, if they choose to put up a fence they can. Now before you say what about Arizona? NM, AZ and CA gave up a 60 ft strip of land going across the whole southern border of their state’s. This was part of the Roosevelt Reservation in 1907, Texas refused. AZ put the shipping containers within that 60 stretch which is Federal property.
