Cops hide in the Bluebonnet cemetery, and if you go even 2 miles over, they zoom out & Never give warnings. I have actually driven into the cemetery & stopped to express my disgust that it is a solemn place, not a place for their speed trap. I used to be a Colleyville resident, no longer live there. But when in DFW, I avoid the city entirely, will not give them even the revenue from sales tax. My money goes anywhere but there.
