Its a Red-bellied Snake [or possibly a Brown Snake] (both species are closely related and completely harmless). The adult Red-bellied snakes are only about 8 inches long (and Brown Snakes are only a little bigger) so it could possibly even be an adult. The picture quality is plenty good enough for diagnostics. You don't need a close-up. The diagnostics (dark head, appearance of partial ring around neck, body color and striping) are all there to indicate the Storeria family which is what Red-Bellied and Brown Snakes are in.

Looks just like the FL Brown Snake in my Peterson Field Guide. Yes, it is a good guy/gal.

Although it seems very skinny, the markings are perfect for a striped California king snake. Check the link below. Tucker Here is a link that might be useful: Striped California King Snake

I have never encountered a snake coming after me. They feel the vibration of humans walking on the ground and skedaddle . While I've been bitten by three dogs and two cats during my life, I've never had a wild animal attack or bite me. My only concern would be my dogs getting involved but I simply take them inside the house for a while and the snake then goes on its way. A garter snake in May in that same area. I suspect he caught the frog because I didn't hear it after that.
