I was on my way to the garden, where Jim was working, when this sight made me stop in my tracks and then cautiously approach. I called for Jim to come and look, and he yelled back, "Get the camera!" He took the photos.
He also had his carpenter's rule in his pocket, and while the coiled snake's length was not possible to determine, the uncoiled one was about 36" long.
It's not every day that you're lucky enough to see a beauty like this right in your driveway.
