As children, we used to go fishing with our parents, into the Everglades, along Biscayne Bay, or down in the Keys. This was before air conditioning in private homes became common. We three kids were accustomed to riding in the back seat with the windows open as far as they would go. The semi-tropical airs could give you a facial windburn if you were not careful. The front seats had a triangular vent window which, when opened, somewhat protected the faces of luckier riders.
We were coming back from one of our secret fishing spots on the edge of the 'Glades, via a dirt road which ran through dry brushy growth. Using a dirt road mandated a slow pace to keep the dust down. Mom was driving when she called to us to quick, look out the back window. She had noticed something in the rear view mirror.
When we did, we saw that a Florida Panther was following our car. It was about 20 yards back down the road, ambling along with a deliberate, loose jointed gait. its head and spine were held relaxed on the same level, as it came. The shoulder blades were working up and down as it lifted and placed its front paws. It was perfectly at ease, ignoring our car and, after we had watched for a short while, it turned to its left and disappeared completely into the brush. It was thin, but healthy looking, as I remember, and it ignored us so absolutely that we had no fear of it.
We would not have gotten out the car, though ...
