This is why some areas on the West Boise Bench were smoky and hazy yesterday. It was a house fire, on purpose. Firefighters demolished this house for training. I drove by several times on errands and noticed that they set fires in different areas of the house, then practiced rescues, then put the fire out, then started another one. At the end of the day, the house was a pile of smoldering ashes. A few days before the practice run, all the large trees near the house were cut down - I assume to reduce the risk of the fire spreading.
