Is there another one near the grass clump on the left?
I only saw the one snake, but who knows...a friend may very well have been waiting for it over there.
When I noticed it I jumped. Does not look like a rattlesnake, but I no nothing of snakes unless they rattle, or rise like a cobra.
I would appear smarter if I read the comments first. But then I would not present as I am. Trying to be honest here.
Garter snakes are the only ones that I am used to identifying.
