Here come de pollen. My white car is a dusty yellow.
I love the phrase "toxic airborne event" for some reason. It featured prominently in an early Don DeLillo novel - White Noise, I think - the one whose main character was an Elvis Studies professor. The government never would say what was in the air, just that it was a "toxic airborne event". This vaguely threatening language covers a whole realm of possibilities, from a really heinous fart to death from above.
