Deep dish is the only way to do pizza. This is just a known fact. Same as that you always go to local pizzerias. I say this as someone who can't really have it for dietary reasons.
As for Gary, Indiana... you're correct, it actually is named after a person. A steel executive whose last name was Gary. There was a pretty solid steel industry there, but Gary is not exactly the best place to be in the Chicago metro area. The reasons why go into interstate politics, so I'll let that be.
