Crews started battling a massive fire on Wednesday at the abandoned Ostrom’s Mushroom Farm near Lacey. Lacey fire officials say the fire could take days to put out as it is at a very large building and burning the over 50-year-old wooden mushroom racks. No one was supposed to be inside the building, as the Ostrom Mushroom Company moved operations to Sunnyside four years ago, but there is a lot of graffiti on the building, so people do have access to the exterior. Chopper 7 was able to capture the huge plume of smoke on the horizon. Lacey Fire officials also say the fire is suspicious. They believe transients were living inside the building. People are asked to stay away from this area. Fire crews remain at the scene Wednesday night and say the flames could smolder for days.
