I was always very cautious going through the close to the Mexico borders areas especially at night. Keep a close eye out when stopped at rest areas... Never pick up anyone.. ElPaso was always a scary place to me at night.
Of course this is the same along any of the well traveled roadways. I95 South would be no different haha...
It has been awhile since I was on I10 but understand now the Border Patrol is making themself very visible along the Mexico Border stretches. Even some check-points to go through.
I was always very cautious of making a wrong turn and end up in line to make a Border Crossing. You hear of this happening alot...
