Saw a really cool spider in Charlotte last week.
(Hah! No Charlotte's Web pun intended).
Including the legs, it was about 3" in diameter and it's back was covered in a rainbow of color on basic black. If I see one again I'll post a picture.
I watch out for the Black Widows, it's the little Fiddle-Backs (Brown Recluse) that you don't see until you're bit. Bad stuff!
