Everywhere in that Austin-San Antonio corridor is being developed, and not just for the rich. The tech boom that has exploded Austin's economy has been going on for decades, and that means lots of new people moving to southwest Texas. Hopefully, it will not change San Antonio and Austin, two of the best cities in the country.
Heh....I don't know much about San Atononio, but Austin has gone dramatically downhill in the last generation.
Very sad; it used to be a place that was Real Texas. Not so much anymore.
Interesting to hear about these developments though. Something similar, though I don't think it's as widespread, is happening in our Wet Valley here in Colorado.
