Carrollton, Texas PD regularly sets up on the west bound side of GW Bush turnpike under the Josey Lane bridge. Their techniques are very interesting; sometimes only one car on the shoulder, other times they'll stack 2 or 3 interceptors up high on the entrance ramp with a shooter down near the roadway with gun in one hand and mike in the other calling out "violators". They use this combination with motorcycles too. This is a regular trap. Be ware!
oh, and at this same spot Carrollton PD was JTG with a ZR3 on July 30th, 2008!
