VIDEO: Sioux City firefighters are facing two extremes, fierce flames and the crippling cold because that's the nature of their job. Imagine if you had to stand out in freezing cold weather, possibly for hours on end because it's your job. Firefighters go through the unimaginable to keep us safe. That includes fires with temperatures up 2,000 degrees and Midwest winters that can be as cold as negative 30. A dumpster fire which happened behind a McDonald's on Sunnybrook Drive on Tuesday served no different for local fire departments.
