Last weekend I was standing outside the doors of a mall in Grapevine, TX (another Dallas suburb) and I’d estimate if I saw 300 people coming and going, 10 of them were white. The other 290 were from India/Pakistan, Middle East, Mexico, and Africa.
The Mills get a lot of traffic from DFW and further South along I-35 though... Grapevine and Southlake usually requires a pretty good level of assets and income to live in.
