As I type this, the air on Grew Hill on the Roslindale/Hyde Park line smells like something's burning somewhere. But this time, the fires are way farther away than Quebec: We could be breathing in the remains of fires in Saskatchewan, Manitoba and the Northwest Territories, as shown on this NOAA map:
