ClarkLZeuss, that is a good idea about making the transfer to another bag before exiting the vehicle. I wondered about that after shutting down last night.
ND7, we are all basing our responses on this line from your OP. If you do this and you are the only person in the room then you are fine. However, if you are the only person in the room and at just the right moment someone else walks in and sees your gun you could be taking a ride. To you, it was an accident that they entered the room and saw your gun, but you did intentionally unconceal it in a relatively public place that you do not own and is not under your control.
Would you do this once in side the place near the front desk if you thought no one was looking? Being in a locker room, while slightly more private, is basically the same situation.
