The past couple of days on my way to work to have seen the GSP up on the Northbound entrance ramp on the 985 exit 8. And they use rear laser most of the time, but I did see them using Ka Band radar once. It looks like a black car, but my scanner programmed to the GSP mobile Ext. frequency always goes off so I am pretty sure it's GSP.
They hide beside some tree's and you can't see them until you pass them one of the most clever speed traps I have seen them run around here.
