I know on the 190 southbound, where the breckenridge tolls used to be, they like to hang out in there.
Amherst:
Weekend nights in the office parking lot just north of average joes on sweet home rd.
Millersport hwy, plaza parking lot just south of sheridan, they love it there.
I have a couple of friends that work patrol for apd, Ill ask them if they know where the traffic cops like to hang.
