I understand what you are saying, i should've been more clear. By annexation I mean Dallas getting others cities and townships to join Dallas. I'm not very sure how cities annex cities, but i do know when cities run out of land they annex townships. the only annexation I know Dallas ever made was the annexation of Oak Cliff(I'm sure there must have been more annexations in the past). I do believe Dallas will be able to annex other cities with our improving safety department and our still developing mass transit will eventual show cities the greatness of Dallas and will make them want to join Dallas. Personally I've never liked all the competition between the cities in Texas. Mainly because I know by the time I'm eighty all the major cities in Texas will be connected as one giant metropolis and you won't even notice when you've left a city. I hope this region gets a name other than Houston, Dallas, Fort Worth, Austin, and San Antonio. A name like Crockett, in honor of what Davy Crockett did at the Alamo.
