When the GPS dies I make a map from the city’s pulse – the hum of traffic, the rhythm of a street performer’s beat, the angle of the sun on the brick. A quick trick: take a leaf, tie it to a twig, toss it, and let the flutter tell you wind direction – that will guide you to the nearest main road or bus stop. If you spot a discarded hat or a stack of newspaper, follow the scent of fresh coffee or the echo of a distant bus engine; those are natural GPS markers. And if all else fails, simply chase the performer’s music – the louder the drum, the closer you’re getting to the main artery. Try it, and see if the bus comes to you instead of the other way around.
