I may have told this story before, Eric. If so, forgive me. Years ago a friend and I entered a museum down here in Florida. He had a camera around his neck and I had a camera in my hand. The guard informed him that he'd have to take his camera out to the car. No cameras allowed in the museum. I chatted with the guard while my friend took his camera out and came back. Then the two of us proceeded into the museum, my camera still in my hand. The secret, as The Shadow* knew, is to cloud men's minds. You have to make yourself unthreatening.
