Oh, one other place:
The backseat of a police cruiser!
No, I was not under arrest.
It was during the Open Carry Walk, I could not find the group who had already began the Walk. An officer, who was already patroling (mostly for us), tried to find them for me on his radio. He told me where and when I still could not find them, he found me again and offered to ride me over there!
Yes, this was even before Ohio's concealed carry law went into effect, when there was no legal means to have a loaded firearm accessible inside a vehicle. He didn't check my ID or anything, just let me in the backseat while open carrying. When he started driving he said, "I just have one request: please don't shoot me." LOL! I laughed and said no, I'm one of the good guys you don't have to worry about me.
This was an officer with the Cincinnati Police Dept. in Clifton. Nice guy.
