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.

Yes, I've traveled the area several times and camped in the NF between I-19 and the Tohono O'Odom. As you can see from the map I posted there is no physical connection between the San Xavier res and the Tohono O'Odom which is called the Papago res on the map although the P is cut off.

This camp they're talking about is a couple of miles north of the San Xavier res at the intersection of I-19 and Valencia.
