That's an amelanistic(albino) Black Ratsnake.

It's impossible to say if it is actually a wild specimen, or someone's escapee pet, as there are a large number of these albino's bred in the hobby, and that area is also a part of their huge natural range.

That is a really nice looking amelanistic specimen either way, congrats!
