The fair is full of high-action fun like rides and rock concerts.
However, many fair-goers are taking a break from the heat to get in on some shopping at the Commercial Exhibit Buildings.
Kelli Volk spoke with some vendors and customers about the variety of unique fair finds.
"What kind of treasures can you find in the exhibit buildings at the fair?
Perhaps the better question is "What can't you find?".
Everything from jewelry, to clothes, to mattresses, and even the occasional teeth whitening service can be found at the fair.
This large market full of variety is what keeps vendors coming back year after year.
(Greg Gantt, Vendor)"We have been here for seven years."
(DeeDee Dreier, Vendor)"This fair--we've been--I believe this is five years, well four years because of last year."
With three different commercial exhibit halls, anyone visiting the fair is sure to find a treasure or two that they can take home.
One customer didn't have to search too hard before finding his favorite item.
(Robert Rafferty, Bismarck Resident)"Just walking around seeing what they have here. Sitting in the swing."
While everyone's opinions may differ in what they find most appealing in the exhibit halls--it seems they can all agree on one thing.
(Greg Gantt, Vendor)"The AC is really nice. We like working inside a little bit better."
(DeeDee Dreier, Vendor)"I almost felt a little bit guilty putting a jacket on when it's so warm outside. But, yes, that part has been very nice."
(Robert Rafferty, Bismarck Resident)"After walking outside for the last hour or so, coming in a building with AC was nice."
