Well now hold on there a second my Buckeye friend!
I was raised in Minnesota, and as a Minnesota boy we were always told that the Minnesota State Fair was the largest state fair in terms of daily attendance. In terms of total attendance the Texas state Fair, which runs twice as long, is the only State Fair bigger than Minnesota.
Now, I know Wikipedia is about as accurate as my senile old Aunt Martha, but here are the attendance figures I found.
The largest state fair by total attendance is Texas at 3,000,000 followed by Minnesota at 1,790,497, Arizona 1,303,690, Massachusetts(New England SF) 1,260,487, Iowa 1,053,978, New York 1,102,995, Oklahoma (OkCty) 1,000,000, California 941,502, Oklahoma (Tulsa) 915,000, Wisconsin 861,408, North Carolina 858,611, Ohio 814,512.
Having been born in North Dakota and raised in Minnesota (I have not been a resident for 25 years) I can tell you there is not much a Minnesotan can claim to be #1 in, 'cause to do so would bring the wrath of God, and hellfire and brimstone would rain down upon the Chevys, Fords, and Volvo wagons.
You can make fun of the Vikings, you can make jokes about the old quarterback with the bad arm, but there are two things every Minnesotan takes to heart...The Minnesota State Fair and Gopher Hockey.
