Wildlife World Zoo & Aquarium, Litchfield Park, Arizona.
Photo taken from some distance, I focused through the square of the chain link fence. I could not get to the fence, it was 10 feet or so away. I picked one square, and centered the tiger's head in it, zoomed and shot. He was enjoying a rack of ribs. If he had not been having dinner I could not have been able to get a shot, since he was eating, he was still.
