The Lincoln County Fair in Merrill has opened as this heat wave continues.
The fair has all the traditional favorites, food, rides and 4-H exhibits.
Because of the warm weather Merrill firefighters are preparing to be ready if fair-goers are overcome by the extreme heat.
Also, 4-H club members are cooling their animals with fans and providing them with cool water.
The fire department is also ready to spray water on the barn roofs housing the animals.
They say that will help cool the barns and make the animals more comfortable.
