This began as a "viewpoint" asking everyone to be cautious when shooting fireworks, but there's a chance we don't be shooting them at all this Fourth of July. The last thing firefighters need right now is a “holiday” dedicated to setting things on fire.It is so hot and dry in Barton County, a spark from a mower striking a concrete culvert started a grass fire on Tuesday. Other fires this week appear to have been caused by humans who were either careless with fireworks or who intentionally started them.Wednesday night’s fires in Colorado were far worse, displacing thousands of people.This week, fireworks went on sale in Barton County, and the first fireworks-related grass fire occurred the same day.
