There was yard waste burning tonight. It did not seem like there were any bonfires upwind.
4:30 PM: No smoke. 88 degrees.
6:00 PM: No smoke. Fresh air.
7:00 PM: No smoke.
8:00 PM: No smoke.
9:00 PM: Light to moderate grass smoke. Somebody is illegally burning yard waste.
9:30 PM: Faint to light smoke from what smells like burning tree branches. This smoke is not being produced by logs in a bonfire. Not that it would be any better to have smoke pollution from chunks of tree. Unnecessary recreational air pollution is never good.
10:00 PM: Light to moderate smoke from what smells like burning tree branches continues. This is not normal bonfire wood that is being burned.
10:15 PM: Light to moderate smoke from earlier continues.
10:45 PM: Faint smoke of same type as earlier continues.
11:30 PM: There is a very faint smokiness in the air at this time. Last check of the evening.
The air was fresh when I woke Saturday morning.
