bamabiker's is a kingsnake of some variety. Not sure about Nasty Nate's species, but I do know he's not venomous (and kind of purty),
that is a gray ratsnake, usually much more of a pattern when young,
often getting more solid toward a mostly black as they get older, eat rodents, small birds, they will eat eggs, once pulled a large one out of a wood duck nesting box with ten eggs in it
