I'm not running with one. Haven't since I got here (like 4 months or so) cause I don't want to put holes in my damn bumper.
Have yet to get pulled specifically for it (though I have been stopped several times and warned for speeding), and I've passed many a cop, either while driving, or when they are sitting watching oncoming traffic. I'll consider putting it on if I get pulled in regards to it.
Requiring a front plate is really dumb though. If a cop sees a car mathcing a description of one that's stolen or something...what do they do...flip a bitch and go at you from the rear...
