Police cruise the two major highways that pass through the city in unmarked Camaros, Mustangs, and Chevy Celebraties. These cars are usually white, but there are red, gray and green units as well. The cars have no give away antannas or lights. I have often seen unsuspecting cars go flying by these units only to recognize them as police units once the dash lights come on. I-25 on the North side of town the units hide past the Paseo Del Norte Bridge. At the same location (facing north bound) I have even seen them use a Department of Highway "cherrie picker" with a cop in the air using a Laser unit and the "Ticketing /chaser" vehicles just past the bridge. Another spot is on Paseo Del Norte (major 4 lane road connecting Albuquerque and the West side of town), they will sit in the unmarked Mustangs on the Railroad tracks behind the highway barracades at a spot where the speed limit goes from 55 mph to 45 mph. Also on that same highway; west bound, they like to set up a cop on the 4th street bridge (laser)with the chase units about a 1/4 mile up on the Rio Grand crossing. One last one also on Paseo; 2nd street on ramp west bound, waiting on the on ramp as traffic comes down the overpass.
