We have some fires SW of here and the smoke it blowing here. Last night it was so thick it looked like a house in the neighborhood was on fire. We were even getting the ash fallout. When I came home from the store today it looked like snow when I opened the garage. We are stuck inside now with the air on high (I'd rather run the air instead of the nebulizer). I'm thankful for the air and my purifiers I have running.
