Certain manufacturing industries are affected by the geography of Texas. Oil refineries tend to be along the coast where large deposits of oil are found and extracted. To keep costs low, you would want to have the 2 close together. Tech jobs tend to be found and centered around many of the large cities in the Coastal Plains area: Austin, Dallas, Houston, etc. The climate has allowed for more people to live in the area and the Tech Industry has gone where many of the people are, which is in the Big Urban, City environment. Cattle Industry has stuck to the North Central and Great Plains areas. Despite the possibility of lack of water, the plains lend themselves well to cattle and other agricultural pursuits.
