So here is the rest of the story. After noticing the snake, I simply grabbed the kitchen broom and attempted to nudge it away from the door so the puppies could get back in the house. The critter attacked the broom violently and refused to yield. So, I left it alone for a few mins and thought it might get the hint. After a few cups of coffee, I attempted to see if it had decided to leave the porch and lo and behold it had decided it liked it there, another attempt to hurry it along by pushing it away with a snow shovel, after being pushed about 10', the snake decided it was going back to the house so I then engaged it decisively. Very, very aggressive and dead set on living with the family. Generally I leave snakes be as they control the field rat population at the farm, but this little guy had bad intentions.
