Driving down National Highway 8A from Ahmedabad to Morbi, even in the sweltering heat, can be a pleasure. The asphalt road doesn’t have a single pothole or bump. Along the way, factories belch out voluminous amounts of smoke and 18-wheeler trucks ferry raw materials to them. What is jarring, however, is the absence of real-estate hoardings — speaking of a lull that mars the business of tile makers in Morbi, whose fortunes are tied to the housing industry.
