I usually Open Carry in NC, but often conceal as well in person, or in the car. Sometimes I don't have the gun on my person but in a safepacker on the seat next to me.

Handguns in Vehicles
It is unlawful to carry a concealed handgun in a vehicle unless the person has a North Carolina concealed carry permit. A person who is not a convicted felon may carry a handgun if not concealed. A handgun is concealed in a vehicle if it cannot be readily seen by a person approaching and if it is readily accessible. A handgun under the front seat or in an unlocked glove box or console is illegal. A handgun openly displayed or in a locked glove box, locked console, or in the trunk is lawful.
