I OC from time to time, TN CCP is for hand gun carry permit. They tell you to conceal carry to keep from being bothered by cops and freaking people out. If I am running to the gun range or hardware store ( mom and pop type store) then I wont bother with CC just OP carry. If I am going out to a shopping center or around a lot of people then I CC. I walk the dog every night in our area and OC every night.
