1:30 AM: No wood smoke. Fresh air.
4:40 PM: No wood smoke. 15 degrees.
9:30 PM: Moderate wood smoke. The air reeks of stinky burning wood. Whatever type of wood is burning is producing an awful smelling smoke. It turns your stomach. The odor of the wood smoke is the same as last night and Saturday the 26th. It is probably the same household using a fireplace and they cannot be too far away.
The air was faintly smoky at 4 AM the next morning.
