I always wondered why everyone would think of Superman as a "farm boy", like he was some kind of hick or something? Heck, Ward Cleaver was born and raised on a farm according to the show, but he never acted "Aw, shucks!" or was TREATED in such a manner.
What makes it so much better to do so to OUR hero?
Then there is Philo Taylor Farnsworth, the inventor of television. He was born & raised on a farm without electricity. And he is considered by many to have been one of the most brilliant scientist/inventors ever.
