Holy cow!Golden Orb Weaver. Very good spider to have around. They are non-aggressive, non-venomous (to humans), eat many, many bugs. They do build large webs (with a tell-tale zig-zag down the middle), but, again, are good to have around your garden. A lot of times if a human approaches their web they will move it to get your attention and prevent you from walking into it. The biggest one I've seen to date had a legspan of about softball size and her web was an easy 4ft long by 2 ft wide.
