I just got a ticket for this a month ago. I now have my plate attached with twist ties. So, I ordered some high powered magnets. Once I install my H/E and pump I will attach the magnets to the inside of the bumper. Then I will attach magnets to the license plate and cover the back of the plate with felt or something so it wont scratch the bumper. The license plate will be bent to contour with the front bumper. Hopefully I can easily pull this off and re-attach it and still have a strong hold. I will have pictures once I get around to it.
