There is a cop on a bike sitting in the median twice a month. The speed limit goes from 55 to 45 and he will ticket you if you go two feet past that sign over 45. Got me coasting thru the sign at 53 mph. When I asked him about it, he said all that mattered was what side of the sign I was parked on. Buddy was ticketed for doing 49 thru it as well.
