Does anyone have a list of Federal Facilities where you can't open carry? To make sure you don't accidentally open carry a place where you are not supposed to.
Also, are parking lots considered part of the buildings? For example a Post Office. Could you be open carrying, but when you pull into the Post Office Parking lot you take you gun out of the holster and lock it up before you go in? Or is the parking lot considered part of the Federal Facility?
