Guys, Check out the "Linemans Handbook" as well as "Electrical Engineers Portable Handbook" the ground wrapped at the bottom of a pole before you bury it is called a "Butt" ground and is a time honored method.
It most certainly is not one we are used to, but NFPA 70 was written for inside electricians not outside. I would think you'd need prior approval before it passed inspection in most local jurisdictions.
