Read an article in yesterday's Austin American-Statesman about the growth of Greater Austin, Greater San Antonio and the areas in between and how the region could merge into the state's third megalopolis in the coming decades. Sounds like leaders from both cities are looking to work together in planning for the future - especially when it comes to mobility along the I-35 corridor.
If you think there's a lot of friction when it comes to the discussion about what to call OUR region, just wait until the time comes for Austin-San Antonio to come up with it's own unified moniker.
