This Gopher Snake is in the bull snake family.
This bull snake chased me around the vehicle before it exited the road and posed for a parting photo.
Great Northern Water Snake
This Midland Rat Snake stopped on the center line for a momentary photo.
This angry bull snake disliked the neighbor's dog circling it and made a rattle sound with its mouth.
Sorry for the not so good photos. I couldn't get up the nerve to get any closer in case I had misidentified this angry creature.
