I feel that yes we have a couple of big cats wandering around but under that same note I also feel they are the Big Foot of modern time.
kind of like the story of divers at every large dam in the state seeing a catfish that was soooo big it made them exit the water and refuse to ever dive their again!
It is funny that you say say that, as I used yo know a diver whose job it was to clear debris from the dam area of lake Monroe, and he claimed to have had that SAME experience - what he thought was a log started swimming away from him!
