We built a fire on the dry riverbed, and settled in for a night of drinking and talking.
Towards dawn, we decided to climb a hill to a ruined castle and watch the sunrise from there. I was most excited about the ruined castle. There was already enough light before the sun rose to explore it.
As I scanned the horizon for the emerging sun, I noticed a white streak across the sky left by a passing plane.
Then I saw another. And another. And another. And another.
More than a dozen planes were criss-crossing the sky in the pre-dawn light.
That was the first real indication I had of just how busy Europe is compared to Australia.
