including the very thought of cross over infiltration of terrorist. While I have no confirm data other than what i was told and thought to be true, the Big Bend region has been a back drop for very serious drug smuggling ( yes, we know that some of this is very true ) by even quick made air strips by the Colombians way out north of Lajitas in past decade/s. Pick up a book on the history of the Big Bend region and see where about 100 years ago it was anything from Candelilla wax to livestock to drugs and peoples. One can even go back farther and see exodus of several cultures going north across the Rio. The very fact that it IS so desolated on the Mexico side makes a entry of terrorist so real.
