Well
excuse me for giving a critical view of the sh#thole I had the displeasure of calling home. I've had too many negative experiences there in my first 18 years of life to really like it or think positively of it.
Let me
try to be positive:
The mountains are BEAUTIFUL. It's unfortunate you need a day permit to hike, but it's cheap. Do it!
While you're at it, take a drive or two across Transmountain and/or Rim Road. The scenic views are killer - especially at night.
The Mexican food IS the best in Texas, but after several years of Tex-Mex in College Station and abroad, I'm not used to the real stuff. If you get a chance, try Leos Mexican Food. They've been around for 60+ years.
The Wyler Ariel tramway is a neat thing to do. The tramway takes you from the base of one mountain to the tip of another. At the top, there's a viewing station which gives you a view of Texas, New Mexico, and Mexico.
If you can visit the historic missions, there's a lot of scenery and history to be learned.
If you wanna go to the racetrack or casino, drive west on I10 until you hit Sunland Park. Good times.
