The 148th annual Kane County Fair wrapped up with so much heat, a battery-powered car driven by a child in the Power Wheels Demolition Derby caught on fire Sunday in the grandstand event. No one was hurt during the competition in front of a large, cheering crowd, baking in temperatures in the 90s.

Full-sized cars also competed for trophies in the main demolition derby. And for the second year in a row, a fifth-grader beat all his adult competitors in the lawn mower demo derby.

“I just came out here to have fun,” said Dayden Charette of St. Charles after he won the event in front of the cheering crowd. His family is the promoter of the event.

The 4-H Blue Ribbon sale took place in the Livestock Arena earlier in the day.
