I've been to India only once, for a week. Not in tourist zone. Chennai, Gorakpur, Lucknow...
People are getting rotten on the central streets, shitting in the city centre at 5 pm is ok as well. i've been hiding from such India in muslim districts because it's much cleaner there. I'm not supporting islam, same as christianity or hunduizm, but I've found those muslim hideouts and was feeling much better there. Travelling to India? Never again
