I have had a permit since I was 18 and have carried daily for the last 40 years. I used to volunteer that I was carrying but stopped after a couple years. Too much hassle from too many officers who don't know or care what the law is. If an officer spots your weapon, your not carrying it properly. If an LEO asks me to exit the vehicle or do something I feel might expose my weapon, I will then announce the fact that I am carrying. The only proper place to keep your weapon is on your person, unless your at home and it is secured. Your weapon is not secure under the seat of your locked vehicle. Most LEO's are good people but most of them are not gunny people and don't understand those of us who are. There is the rub, and I find that discretion is the better part of valor in those situations.
