Driving into town a couple days ago, I went through a driver's license checkpoint manned by two of our NC State Troopers. The young trooper who approached my vehicle looked to be in his early 20's. It went like this:

HIM: Good morning sir, may I see your license?

ME: (with both hands on the wheel) Yes, but first let me tell you that I
have a concealed carry permit, and my gun is to my right,
beside the console. My license is in my right hip pocket.

HIM: OK, I appreciate you telling me, and I appreciate you carrying. You
might save my life someday.

ME: You never can tell.

HIM: (after checking my license) Have a good day, sir.

ME: Thanks, you too.

Not the first time I've been thanked by a LEO for carrying...
