If you drive either direction on 635 between the Greenville and Northwest Highway exits you've probably seen the newer black DPD curisers parked on the median and 1-2 cops hanging out with radar guns. My question is since I've never seem them with anyone pulled over, or even look remotely interested in doing so are these guys using some sort of handdheld photoradar guns and just mailing tickets out?

 

In my experience, they like to use laser on that section of 635.
