Fort George G. Meade, Maryland Speed Traps

At least 3 types of radar detected by Cobra 11-band radar/laser dectector. Both in X and K bands. One type is emitted by the portable "this is your speed" sign. The cops use the two other types> I’ve only seen them use it in their cars, not on foot outside the cruisers. Seen them on Mapes Road, Rockenbach road, the road behind the PX where the Burger King is, the housing areas, and Cooper Ave.
