MINNEAPOLIS (WCCO) – A doctor at one of the State Fair’s medical aid stations said about 20 people were treated for heat-related problems on Thursday, when temperatures were expected to soar into the 90s.

However, none of those treated had to go to the hospital.

The doctor said the heat kept the crowds small and people were dressed appropriately for the weather.

Last year, a 90-degree fair day sent up to 30 people to aid stations and 11 to the hospital.

Fair officials, who prepared for the heat with bandanas, cooling stations and air-conditioned buses, say there are still bandanas available at information booths while supplies last.
