39. He can say Dallas but it is Highland Park ($$$$$$$$)
The Bush family didn't live in the Town of Highland Park before, and I doubt they will in the future. Highland Park is too "crowded" and none of the really big estates are ever for sale.
The President lived in Preston Hollow before, which is an area of the City of Dallas. That's were the Perots live, on Manson Ct. Most of the estates are on vast land (for being in a big city). It's possible to live in Preston Hollow and no one will ever find you.
