I went ahead and took the snake back to the lake and let it go around where it was captured. Hopefully next time my friend leaves the snakes where they are. It wouldn't of been such a big deal but the snake was endangered to begin with. I sometimes go herping and I live in Illinois, I just take pics and then release the snake though. I have found every type of snake except a timber rattler, they seem impossible to find. The only one I have ever seen around my area was someones facebook post of one and they cut it's head off
