Jim Finn was inspired upon visiting big truck shows in the mid-1990s.
The Mantorville man started up the Big Iron Classic truck show, for semi-trucks and trailers, in 2000.
It has grown.
Finn estimates that, depending on the weather, around 20,000 people will visit this year’s 18th-annual Big Iron Classic Truck Show and Charity Drive, Friday and Saturday, Sept. 8-9 at the Dodge County Fairgrounds in Kasson.
