I saw a spider that looked almost just like that last week!! It was HUGE too! The only difference was the big round part of the body was more of a cream/white color. It was hanging out by the big hole in our front porch (also a snake hangout). It freaked me out! I didn't kill it, just went in the house...if it was in the house things would have been different. I keep looking for the spider, I want to see it again and show it to my mom. She doesn't believe me that it was that big!
