I see what you're saying about running alongside the San Xavier reservation, which is affiliated with the Tohono O'Odom res., but that res. doesn't border Mexico.

That reservation extends across the Mexica Border way west of I-19. In addition a National Forest borders the Mexican line between Reservation and I-19. Forest goes north and is another path for illegal entrants.

You csn enter that National Forest about 5 miles east of I-19 and 5 miles north of Border. Great target practice out there and sad monument to felled BP Agent. Not Terry.
