I hate the idea of drilling holes in my bumper, specialy now it is seven years old.
I work with Leo's training them how to fly uav's so I guess I should respect the law, well, if I can find a plate holder. I have never used a warning system but I do find my self blowing yet dust out every once in a while :-). I do kid the locals by telling them I can out run their radios with communication scramblers, funny.
I have not had a ticket since 76, crap do I date my self. Radar detecter humm, some thing high tech to play with.
