Creepy Critters

Today, as I sat working in my office, which overlooks our courtyard, I spotted some motion out of the corner of my eye that registered as unusual.  When I looked up, I saw a 4-5 foot long snake slithering around the courtyard.  I'm not too afraid of snakes, unless I know they are going to bite me or are poisonous.  I don't think this one is dangerous, at least he doesn't look like it.  I still hope he doesn't slither up on me ever.  He stayed put for me to get a few photos.  

I thought we may end up having a National Geographic moment on our hands, but the snake slithered on by, leaving the lizard to see another day.
