Western Diamondback Rattlesnake

I gave this one a good look too. I think the ID is correct based on where it was found along I-10 near the Nevade border. Southern Pacifics don't make it that far east and Mohave's don't make it that far south. Southern Pacific's also have a brown/tan/yellow terminus to the tail before the rattle. More photos could convince me in a different direction especially since it is near an interstate and people have been known to move snakes out of their range.

Any other pics of the snake? I can tell it isn't a Western Diamondback (lacks prominent black and white banding just before rattle.) Possible Southern Pacific, that would be my guess with lack of body to go by.
