Check you're state laws. That's you're best bet.
I know in GA you can cary any hand gun in a holster on you're side,In a locked compartment in you're car or in the open in you're car with no license. I know in GA you can not be within a certain number of feet 300 i think when carring a hand gun from a school zone enless you live so many feet from it.
You can get a concealed cary permit and put it where ever you want. Here it was 45 bucks and you get them at the court house.
