If your at Ft. Meade, Urbanlegend is there and he has a Silverstone M3.
Nowadays, the cops are getting smarter. I have an escort 9500ix and it doesn't go off when I approach a lot of these cops parked on the side of the road. Now, what they are doing is to switch their radar on when they see a car going faster than the flow of traffic. Before, the detector would go off all the time and I'd spot them a mile away which was when they'd sit with the radar on all the time.
