Barb Schaller, 64, has been competing in state fair competitions, mostly in canning, since 1981. She called the Minnesota State Fair the "best 12 days of summer." Her favorite food: vegetables on a skewer.
"It's the one time of the year when you get to eat certain things," Schaller said. "I don't fix corn dogs in my house, ever, and my husband goes to the state fair just so he can have a corn dog.
"The other thing my husband likes is the little mini donuts," she added. "That's the only time of the year he eats them, which is probably a good thing since most of the food at the state fair can be put in the food category of fat, grease and sugar."
Fran McLellan owns the Shrimp Shack, selling grilled shrimp and fried shrimp, both -- you guessed it -- served on stick.
"When people come, they like anything that's on a stick or deep fried," McLellan said. "Those are usually big sellers. It's just a tradition we have here."
The Minnesota shrimp man said that, often, when you eat out, food is overpriced. But not at the fair, which adds to the appeal. (He sells his shrimp on a stick for $4 a pop, and two for $7.)
Marjorie Johnson doesn't eat the food as much as enter in baking competitions. Her first one was in 1974. Since then, she has won more than 2,500 ribbons, including more than 1,000 blue ribbons. She has written a book, Blue Ribbon Baking with Marjorie, about all her prize-winning cookies, cakes and rolls. She even once baked Jay Leno a birthday cake.
"Once you enter and get a ribbon, you are really hooked," Johnson said. "It's so exciting and wonderful when you win a ribbon"
Johnson is more into baking than the junk food. But her kids used to always get the candy floss when at the fair and she is always surprised by what new calorie-laden meal is put on a stick.
"I guess people just love to eat," she said. "The smells are wonderful. Oh, all those wonderful smells. … You get hungry walking around and seeing all the exhibits."
