Dallas is the most populous city in the dallas fort worth 
I have never been to Dallas, how many people live there?
In 2010 when reported it states that 1.1 million currently live there
Do you know what would be a good time to visit Dallas?, sounds like a hot city to me
not much information on when to visit but i would say anytime of the year, another fact is that texas is known to be the center for the oil and cotton industries.
Great, know of any interesting places to visit there?
Dallas would be a nice place.  Very highly populated city with lots to do
