[Local knowledge]
A large metro calls for careful planning.
The Dallas–Fort Worth area is not one city. It is a network of neighboring cities, four large counties and long commuting corridors. A person can live in McKinney, work in Las Colinas and spend the weekend in Fort Worth. Any investigation here has to account for that spread.
Our private investigators in Dallas plan around the way the Metroplex actually moves. Rush hour on US 75, the LBJ Freeway and the Dallas North Tollway can change a surveillance plan in minutes. Toll roads such as the President George Bush Turnpike and the Sam Rayburn Tollway let a subject cross several suburbs quickly. Records may sit in Dallas, Collin, Denton or Tarrant County depending on where someone lives, works or does business.
