A fire in Sherman County on Wednesday night burned over 100 acres as firefighters battled it well into the early morning hours.  The fire originated near Highway 97 four miles north of Moro between DeMoss Park and DeMoss Cemetery at about 7:30 Wednesday evening.  It was pushed by strong east winds blowing 30 to 40 miles per hour, along with very dry conditions.  Reports indicated the fire was nearing mop-up at around 1 a.m.  Firefighters from Moro, Wasco, North Gilliam County, South Gilliam County, North Sherman, and South Sherman fire departments were joined by area farmers and ranchers in responding to the blaze.  There was also a small grass fire Wednesday evening at the Hook in Hood River near the railroad tracks.  It occurred around 6:40 p.m., and Hood River fire crews were able to quickly extinguish it.
