VIDEO: Karl Harris has been fighting fires for 35 years. For the last 14 years, he's worked for the Iowa DNR as a fire specialist who teaches certified classes across Iowa for wildlife fire, and helps build and maintain some of the trucks used in wildfire situations. His work with the DNR isn't just in Iowa. Harris has driven those trucks, type-3 engine vehicles as they're known, out west to help wildfires like those ravaging hundreds of thousands of acres of land in California. "Usually when they call people from Iowa, there's so many fires going on at the same time that they run out of resources in their area or region," Harris said.
