" Six thirty and I could hear the gulls coming and going over the cliff and the now familiar early-morning battle with boots and tent flaps took far too long. As soon as I stood up I was overwhelmed. Not only by the desire to sit on a white, shiny, flushing toilet, but mainly by a wave of vertigo. Somehow in the dark and fog of the night before we had pitched the tent two meters from the edge of the cliff. Tent, path, scrap of grass, hundred-meter-drop. I regained my balance and looked for somewhere slightly disguised. All I could see was an open hillside with a small clump of gorse bushes. There was no waiting; it would have to do. I frantically tried to dig a hole with the heel of my boot - we hadn't carried a trowel for this, far too much weight and anyway we'd always find a public toilet. My thumb ripped through the waist of my leggings in the rush as I squatted behind the spikey sharp gorse with as much relief as Renton in 'Trainspotting'...
'Morning. You found somewhere to camp then? "
