Via Laura E. Goodin I had seen this amazing archer before but Laura reminded me about him.
I'm not sure where I came across this but the photos are breathtaking.

And one more. I was researching cave living when I found these.
And finally an ad from Air New Zealand which doesn't take itself too seriously.
