The historic home next to Hardee’s burned Monday night, the large two-story structure expected to be a total loss.“We don’t know the cause,” said McMinnville Fire Chief Kendall Mayfield of the 11 p.m. blaze that ravaged the unoccupied house owned by John and Shirley Douglass. “It’s not really safe to have someone crawling around in there because the walls may fall in. The back end is practically gone.”McMinnville firemen battled the blaze for hours Monday night and into Tuesday morning as flames spiraled into the night sky, visible for miles from downtown.
