Firefighters responded to Hodag Country Fest this afternoon for a reported camper fire on the main grounds. A member from Crescent fire dept. was on the grounds and responded to the camper to give us a size up. He was able to knock the fire down until our first unit arrived. The fire was contained to the refrigerator. Firefighters used water extinguishers to extinguish the fire and then remove then contents in the fridge outside. Firefighters were on scene for 1.5 hours.
