Nonsense. I work for a fortune 500 oil and gas company in downtown Houston. There are plenty of employees who are from both A&M and UT... as well as other in state schools such as UofH and Rice University.
There are people who also internship here from all over the country. Guess what? My company is not the only one in the downtown Houston metropolitan area where you would find many people working in oil and gas from both schools and many others. Just like A&M hire their people, so as many other universities/colleges.
Back to on the track & cross country: The University of Texas has the edge on Texas A&M when it comes to the distance athletes. A&M has been doing excellent with their 800 meter athletes and their sprinters are doing well. However, Texas distance program is the best in the state and one of the best in the nation.
