No tags in the front either for me. Have been running my M3 in Maryland since July 08 and no problems. Parents live in DC and I travel across all 3 (MD, VA, DC) all the time without any problems so far. Also helps that I don't have a front bracket mounted so I can always point to that and my military ID and show I purchased it in Germany and say it never came with the part ordered or attached!
