Thanks for the clarification. I remember visiting a friend who lives near the stadium and having to drive across the county line to buy a case of beer at a store.
Maybe the store alcohol sales laws are different.
They are. They have to be in a wet area. And the areas are different for beer and wine than they are for hard alcohol. I don't keep up with the current lines, and I know the law was loosened last session, but basically if you want package hard liquor in north Dallas, you have to go to the Colony, a small strip on Buckingham in Richardson that used to be an independent city, Inwood just south of Addison, or a few other locations. East of Central and south of the Railroad tracks that run south of Royal; Northwest Hwy westbound from Central west of the railroad tracks, etc. Package beer and wine is somewhat more available, but again, you have to be familiar with old precinct lines to find it.
I don't know what areas around Irving are wet or dry, but I wouldn't be surprised to find that you had to drive a few miles to get a package. In Plano, wine and beer are freely available at grocery stores, gas stations, and free standing beverage stores and beer barns, but you are going to have to drive to another city to buy a bottle of liquor. Most restaurants are members of the same 'club', so one membership works anywhere in town, and may work in Frisco.
