I’m 100% certain it’s not a snake belonging to the Crotalus genus, or even in the entire Viperidae family. I’m also 100% certain that it belongs to the Pantherophis genus and is specifically the p. Spiloides. Slightly keeled scales, round pupils and at the end of the ventral scales is the scale over the cloacal the tail scales ( subcaudal scales ) are double rowed. Color scheme is gray and black with reddish hints under the keeled portions that show up when moving. I use to visit this same snake for around 4 years where it lived in a specific giant log until the unfortunately created a road about 20 feet behind this part to connect to a new rv camping ground. I’ve handled around 30 different species of snakes in Alabama and Florida and well over a 1,000 different snakes in the last 10 years. My goal is to find the roughly 56 species and subspecies of snakes in Alabama and handle them including the pit vipers and corals.You sure that's not an Eastern Diamondback? I saw one in Florida; them suckas are huge! (And I bloody well wouldn't pick one up.)
