The main thing to think about is this: If it is not illegal according to state law, I don't worry about even looking for signs. It is CONCEALED! If I were caught and asked to leave a place that is posted, I would leave.
Agreed, I'm not going to take off my gun every time I go somewhere. What would be the point in carrying at all! It's a ''CONCEALED CARRY PERMIT'' so just keep it concealed.
