Two large fires a couple years ago were simply due to someone legally target shooting, and the .22 shell accidentally ricocheted off some rock and generated a spark. People pulling off the road and parking in dry grass can do it. One case this year was deliberate arson. And kids with fireworks started that terrible fire in the Columbia River Gorge. I've personally seen fires due to both firecrackers and cigarette butts tossed out car windows that spread faster than you could drive. In one of those instances I encountered a Forest Service office about 15 miles ahead (in a slightly different direction than the fire was moving). I ran in and tried to speak to them; but they told me to leave because they were busy on the radio communicating with a fire crew on the other side of the pass. So I yelled at them, If you don't get off your butts and listen, twenty minutes from now neither this office nor town will still exist! That got their attention, and they stopped it outside of town. Lucky it was just a grass fire that time.
