When I was in the Navy, a bit more than 50 years ago, I worked in Meteorology and if I were reporting the weather, I'd would have had to call the sky in SW Michigan obscured which meant the smoke was so thick you can't see the clouds. I think Trump should sue the Canadians for allowing the conditions in their country get so bad my health is endangered. You know, kind of like suing gas producers for the pollution caused by drivers. Cars don't cause pollution if people don't drive them, so ultimately the drivers are the cause.
