EEEEEWH!!

I found this bug in the church parking lot one day, and mustered up the nerve to pick it up. Well I was going to be brave and pick it up with just a Kleenex, then it moved (slightly), so I went into my preschool room and grabbed a Ziploc bag, and placed it carefully in there. I was horrified and intrigued with this insect? I've never seen anything so large. The picture really doesn't do it justice. It was as large (in width and length) as my thumb.I know he was tucking himself in for this picture! (haha)
Anyone know what it is for sure? My guess is a cicada
