From what I’ve seen online, it looks like a gopher snake, non-poisonous. The round eyes and somewhat pointy head is a good sign.
We’ve seen king and rat snakes, along with blue racers around here. My wife wants to kill them all, but I say leave 'em be, they help control the rodents.
My bro-in-law tho, recently killed about a 40in timber rattler over at their place. It was coiled up under the bush hog (mower) when he was about to hook it up! Very lucky to not got bit. He had to smash it with a fence post.
