Border towns weren't the true Mexico back in the day and the resorts never have been. Unfortunately the cartels have made it impossible to safely tour interior Mexico.I walked across at Del Rio TX/Acuna MX with family back in 2009 after hiking 30 miles at Big Bend National Park. It was neat to see a true Mexican town, have a beer 25 cent Dos Eqquis and some of the best margaritas I've ever had at 19 years old. Also bought 3 fifths of premium tequila for less than $15 total. I'm glad I went back then, but there is no way I would go now.
