Mid-Columbia Fire and Rescue crews Tuesday dealt with a 12-to-15 acre grass fire west of The Dalles between Highway 30 and Interstate 84 near Pinewood Mobile Manor.  According to MCFR, crews during the late afternoon went into a mop-up phase with the fire still burning in hot spots and parts of some railroad ties are smoldering.  The fire did jump to the north side of the freeway, so firefighters were working both east and westbound sides of I-84.  The fire call came in at about 10:30 a.m. Tuesday.  Dallesport, Hood River, Oregon Department of Forestry, and U.S. Forest Service crews along with Klickitat County EMS were all assisting MCFR crews.
