Here's a couple of Knoxville, TN Black Rats that I came across in the past several years.
The first one was last year on our local Disc Golf course. Jumpy, but no interest in biting me. I would guess about 2 years old. Washed out and brown, it wasn't that nice to look at. Bad phone pic - sorry.
The larger one was especially docile and quite stunning. I rescued it off a busy road while trying to cross. That was the largest snake I have ever come across in the wild, let alone caught. I think that was from 2007 maybe. VERY strong and impressive. My daughter wanted to keep it, but I convinced her it needed to live out it's days as it always had - wild and free.
Both released after pics were taken.
They might not be the best looking snakes out there, but the Black Rats are some of my favorites.
