Every year in summer, Jitendra Nath embarks on a long and arduous drive to Ranchi, his hometown 1,235 km away. Nath, a businessman who runs an event management company in the national capital, can afford to fly. But he still prefers to drive through cities en route to catch up with his batchmates, many of whom are in the civil services. He religiously hosts reunions and is a regular fixture at these get-togethers.
