My favorite activity at our state fair is this booth where you throw dimes at a bunch of plates/cups. If your dime lands in a cup, you get to keep the cup. I've spent like $10 each year on that damn game, and have only won one cup. And it was a sucky one.
I don't go on the rides because I have a sensitive inner ear. I have bad memories of me as a child--McDonald's cheeseburger, fries and a vanilla shake pre- carnival ride= BAD idea.
