I have been OCing for about a month now, I haven't had a single stranger say anything to me..........yet. I'm still waiting for my "first hassle" as well. While I'm waiting, I've been preparing; you might want to do this as well. I have all of the gun laws for NC printed out and put in a binder. I store this binder in the car and have it ready in case I get hassled by the police or someone wants to know more about OC. I also have a small video camera that fits nicely in my glove compartment. I plan on getting some extra batteries for it. Also, as a backup my cellphone also works as a video camera (the audio stinks on it though, which is why it's a back up.) I suggest doing what I do; that is, enjoy the freedom of openly carrying a gun, but be prepared for WHEN not if, you get stopped and hassled. It's going to happen, the longer it doesn't the more you can be prepared.
Lastly, and this is not a promo for Opencarry.org, but keep reading and following this forum, go back in the archives and click on the threads that deal with folks who have been hassled, and learn what they did, or shouldn't have done. I know by doing all of the above, I was not even nervous at all when I first OCed (Harris Teater).
