The snake is still hanging around our house. He was in the bushes in the front yard when my parents got home. My mothers solution was for Dad to catch the snake and toss him into the woods. He would then need to bleach himself before he would be allowed back into the house.
The snake is still, so far as we know, in our yard. Non-poisonous, so I vote for letting him alone. They're great for rodent control. I'm still hoping to get a picture of him. I went looking last night, but he'd already high-tailed it to a secure location.
