Sahara Dust

This was Athens four days ago:

Sunny, bright, clear, lovely.

And this was Athens yesterday:

See the city straight ahead? No you can't. All you can see is dust. Dust, dust, dust. 

Every once in a while, dust from the Sahara comes blowing into Athens. It coats the cars, grays out the sky, and gets stuck in your teeth. 

Maybe I just have giant teeth gaps.
