What is it like to be blind in a city known for its potholes, dug-up roads, collapsed flyovers, savage traffic, rotting garbage heaps and suffocating crowds for the last 40 years?

I'm talking about Mumbai, of course, a city that has looked ruined and bombed out as long as I've lived here. Roads are perpetually potholed and under repair; flyovers collapse; pavement are always being dug up for laying one cable or another; mounds of garbage fester in the middle of thoroughfares, scavenged by stray dogs, cats, crows and cows.
