Have you been to the city of Dallas?
I actually went to Dallas and later Fort Worth not too long ago for work. That is a very large population center.
Have you watched any of the sports teams in Dallas?  They have a really good basketball team, football team and hockey team!
I don't watch much of the NBA, but I do watch Football and Hockey.
The Dallas Stars and the Dallas Cowboys?  Have you been to any of their games?
I've been to a Dallas Stars away game when they were playing the Tampa Bay Lightning! They play periodically even though they are in different Conferences.
Is it also true that in Dallas, you are allowed to possess a gun?
Gun laws are pretty open in Dallas. You can own, sell, transfer and modify guns as a civilian in most of Texas.
