Dude... sorry, but you are deluded. I grew up in Corpus Christi and the highest point of land for 300 miles is the landfill. I think the new REc Center at TX AM Univesity-CC has a wall, but it's not very close to S. Padre....
Hey I have never been there, I am going there on vacation with the family and didn't know what is out there. I am from So.Cal where you can climb anywhere.
