I went to the barn early this afternoon, it's windy as heck here, and 14 degres out so I figure I get horses in an hour earlier. I get home feed cows,and go in basement to warm up, take ashes out of wood stove, then to lock up hens. Walk out of my basement to dump ashes on the Icey driveway, I look toward my brothers house to the east of me, and I see a glow, I thought the moon looks funny, than I realize he had a chimney fire. As I'm walking up my back yard calling his phone, he comes out of his house, about 250 feet away, I yelled your chimineys on fire, wind musta carried my voice, he heard me and bolted inside to close the wood stove damper. Well we went on the roof and watched, make sure no sparks caught the roof on fire, after about 1/2 hour everything looked ok, I think he dident clean the chimney enought, for that much creosote to build up. He was glad I was outside and saw it! Locked up the hens and I'm trying to thaw out now, the wind on the roof was unmercifull.
