Gray Rat Snake, maybe? There is nothing like the fright you get when you open the back door to let the dog out and you see a snake looking back at you… I’m pretty sure this snake was taking advantage of all the new baby lizards scurrying about.
I had to remove him from the porch, before the dog investigated or he could crawl in to the house, eeek! I found the broom, set it on top of him, until he crawled on to the broom. I lowered the broom to the ground, gave it a firm shake and watched him slither off in the opposite direction.
