I'm normally used to the usual large spiders, being from Texas,(tarantulas, orb weavers, wolf spiders, garden spiders, etc) but this one was new to me.
Found this guy in our backyard, in a bath mat that had been thrown into the yard. Including links to more pictures, to help aid in identifying. In the one picture, that is my hand, not a child's, he was pretty big. And it is not very visible in the photo, but he had bright orange stripes running down either side of his back.
This could be a Carolina wolf spider, Hogna (formerly Lycosa) carolinensis - see http://tinyurl.com/cacejn for an image. It is the largest wolf spider species in North America; I've seen one with a leg span approaching 4".
