India’s Thar Desert isn’t Peter O’Toole desert, too scrubby for that, but still desolate enough for a bend in the road to be viewed as a major feature. You can pass a hundred miles of nothing and then something. Like this – a perfect circle of a dozen sheep, their bowed heads facing inwards and touching as they doze, matched by another circle a quarter mile ahead. No one knows why. Maybe they’ve learnt how to shade their heads from the heat which can top 48 degrees; maybe they’re just attention seekers, and who could blame them?
