I guess you're getting the smoke from north of the border. Nasty.

We've been dealing with our own nasty fires and smoke out West. The combination of drought and sustained winds are playing hell out here. I'm safe -ish where I am, but 2 hours west there are new evacuation orders just issued.

Good call on the N95s. I know people here (guys, naturally) who "toughed it out" when the air quality was 10+, the worst rating, off the scale. They were physically ill the next day; that fine particulate chemical soup goes straight into the bloodstream.
