@speechie - Wow, I feel like I won the trivia lottery because I can answer both your questions!
The Navajos live in the Southwest part of the United States. To help you jog your memory about Navajos, they were considered great warriors and they farmed until the mid seventeen hundreds. During this time they lived in and around Arizona and began herding sheep.
And as far as Hulk Hogan, I know of course, that you probably assumed that Hulk was not his real name but Hogan is not his real name either! His name was Terry Bollea and Hogan was used to be representative of Irish Americans (as Hogan is actually an Irish name as well derived from a few different names such as O'Hogan).
