Gators been in the Trinity system and Denton Creek/Grapevine for at least the last 45 years that I know of. A huge one was ran over by a car on Trinity Blvd. a few years ago down behind Bell Heli plant in Hurst. Made the news papers. The big boy that lived up in Marshall Creek on GV is probably dead from old age by now.
From Genesis: "And God promised men that good and obedient wives would be found in all corners of the earth."
Then He made the earth round...and He laughed and laughed and laughed!
