Ha'amonga 'a Maui
Waited ages to take a phone photo of the "Tongan Stonehenge" without any fellow tourists in the picture. Snapped a bunch because it was bright sunlight and hard to aim/frame. Got back on the idling tour bus, checked them and realised I'd accidentally selected selfie mode. So instead of a mysterious ancient structure, all I could see was my own ugly mug. Deleted the images in disgust. Suddenly, the bus lurched forward and I had *just* enough time to shoot the following pic through the window. No posing tourists visible - only half a frickin' tree!
