Not found on my commute, but interesting nevertheless: earlier this evening on a rural road, my wife and I spotted two kittens in the road eating this:
It was a scarlet king snake, about 18" long. At first we thought it was road kill and the kittens were just scavenging, but it had some puncture wounds and it wasn't crushed. The little hunters didn't stick around, but I tossed the snake into the bushes after them to keep them out of the road.
About an hour later we found a 4' long yellow rat snake that was very docile, I helped her across into the bushes.
