What's a road lizard?

I don't know what a road lizard is. Can't say that it's really an animal. I've heard of a road runner (saw one too...not as cute as the one on Bugs Bunny though.) Heard of road kill (saw lots of it growing up in the back woods of northern Louisiana...yes, people really do stop to pick up fresh road kill for dinner). Heard of road rage (proud to say that I haven't run anybody off the road or given a one-gun salute...but a lady was cussin' at me today for pulling out in front of her. I didn't care that she was mad. My car was bigger than hers.) But, I can't explain what a road lizard might be. Anyway, it's what one of my former bosses used to tell me, and I quote, "Girl, you crazy as a road lizard." Maybe he was on to something. Little did he know that my dad nicknamed me "Kook" (as in cukoo or kooky) when I was yet a tyke. He thought I was crazy even then. I'm not really crazy, I just say what most people are thinking. Oh well, This blog will give you a chance to see the world through my eyes. Everything's funny if you look long enough...you've just gotta stay focused!
