In Oregon, there aren't any Bullsnakes (Pituophis catenifer sayi), but rather two sub-species: Great Basin Gopher snake (Pituophis catenifer deserticola) and Pacific Gopher snake (Pituophis catenifer catenifer). And yes the Night snake is up there but is a rather small snake compared to the Gopher snakes.
I hate doing small snakes, a nice sized snake (3-5 feet) is easier IMO.
Let us know how your snake comes out when you do one.
