Ok, a little full disclosure: I am a vendor at the Minnesota State Fair. I have been for my entire adult life.
I own two food stands--Real S'Mores and World's Greatest French Fries.
Neither is an exaggeration.
I know from experience the Great Minnesota Get Together is a microcosm of the national economy.
Even though the Fair is a highly regulated marketplace, food vendors must still practice the fundamental principle of business—selling a quality product at a reasonable price--along with strict observance of the 3 immutable laws of real estate—location, location, location.
The Wild West days of petty graft and nepotism that could occasionally be found when the Fair had trouble finding enough exhibitors and vendors, has been gone for decades. Today, the operations of the Fair are professional and squeaky clean.
The State Fair shifted deftly with the national economy of the 1940's and 50's, morphing from a "Food Production" exposition to a "Food Consumption" spectacle. Like the state's diversification from farming to manufacturing, mining, tourism and technology, the Fair graduated from feeds, fertilizers and farm implements, to a free-for-all for foodies.
The ludicrous diversity of ingenious food products, which today features 300 offerings appealing to every pallet, reflects the changing face of the America outside the Fair's gates.
