I finally got my game warden to admit we had panthers everywhere in suburban Austin which everybody knew. Then a guy caught a freshwater shark in Lake Medina a couple years ago.
There is a mountain lion and cub in the area of the Lago Vista Middle School / High School too. That means there has to be a male mountain lion as well.
When I was a park ranger until the end of June, I heard some hair raising growls at night near a POA building on Boggy Ford.
