I just recently removed my front plate on the premise that nobody seems to care around here and, with my Cadillac down for a few days to have some well-deserved updates, I decided that I didn't like the look of the DMCH bracketed plate on the front. I'll keep you posted, but I expect no problems.
On an interesting note, I keep a novelty Illinois plate on the front of my Dodge; "BDR 529" and it expired in 1980. Nobody's ever questioned that or even said anything about it and I've only been pulled over once with the car; for possible suspicion of drunk driving due to original, worn steering components.
