There's something in the air

For the past couple of days it has smelt like the sea in Toronto. More specifically, the sea from a beach at low tide, when all the seaweed is there.

I have been happiliy smelling the air, thinking of the ocean. Except everytime the air smells different in Toronto, it's because something weird is happening. Like the sewage system is messed up, or there's been a zebra mussel explosion in Lake Ontario, or a plague of aphids.

So I need to use caution.
