Planning on heading down to the DFW area this summer to hit up Six Flags? It’s looking more and more likely that you’ll be able to enjoy the rides and, for the first time, grab a beer while you’re at it. The administrator of the Texas Alcoholic Beverage Commission announced this week he has signed an order clearing the way for alcohol sales at Six Flags Over Texas and at the Six Flags Hurricane Harbor parks. The city of Arlington had been fighting the move — which was also cleared by a local judge — but now officials there say they won’t appeal. Six Flags opens for its 2009 season tomorrow; a TAB Commission spokeswoman said the park’s license could be issued by March 20.
