not that I've ever seen...
What a co-incidence! I go to Bruceton, Tn. every year to visit my in-laws every year which is only 8 miles from Huntingdon on Hwy. 70 halfway to Camden,... cruise some of the backroads though and there's plenty of Black Rats and Black Racers. I've also seen plenty of cottons and Timber Rattlers down there. That's an awesome part of the state... Good Luck!
