Tombstone,
I can tell the scale from the background asphalt. That rattler wouldn't have fit around your big head! Besides, he's a fairly young one (count the rattles). Leave him for another day.
I'll ask my brother if he has kept any of the skins from his recent kills (He's been clearing the barn at my sisters ranch.) One was over six foot and the other over five foot. Maybe a hat band and a belt!
