So, I just did a quick scout now to find a picture that grabbed my eye.
It's San Francisco, taken from a helicopter, by photographer Michael Shainblum.
I like the colours, the contrast of the beauty of nature against the beauty of the urban landscape.
I love how it makes you feel tiny and huge all at the same time.
It looks so cool and you can almost feel the icy wind whipping through your hair - it takes me back to my own (ground level) adventures in San Fran.
What's the coldest you've ever been?
