I saw one of these in one of those older posts so I though i'd start another....
So here's what you do: Take the state you live in and say things only people from your state do.
You know You're From Montana When:
People you don't know smile and say "Howdy."
You can actually pronounce the City's name Glasgow (Glasgo) without calling it Glascow
When the car in front of you is weaving, you suspect a farmer instead of a drunk
The pickup trucks all have two rifles and two big dogs.
The gun show attracts more people than you thought lived in the whole state.
You know the meaning of "amber waves of grain".
You know what bear grass is.
You know where the Bears Paw Mountains are.
Soda is called pop and you laugh at those who call it soda.
I could do tons more but i'll just stop there.
