I've noticed a couple of times while driving through the hood that when there are a couple of cars parked in front of a home for sale that my K band will light off around 100 yards away from the house in question (real short ramp up). I don't see these cars that often so I'm assuming they are the real estate whore's cars. What's weird is I don't see any detectors in the windows of the FJ and Accord that were parked up front. Is this a concealed K band leaky detector or something else? The same two cars are parked up front and when there are the only times that I experience this phenom.
