I encountered this large spider in a defoliated parking area for a nature trail in New Orleans City Park. Actually my daughter noticed it and jumped back. It's about the size of a silver dollar. It was very docile in the sun and started hopping several inches at a time when I shooed it away. Can't find a match on Google Images or any insect info sites. I thought it looked like a large wolf spider, but the size and orageness of the head don't seem to fit.
