Day 3 after the conference
Went on a train from Agra to Delhi, and then to Mumbai(distance 1500 km). We got a ticket to an overnight express, first class for 30 euro 1500 RS. We got 3 free meals and nice service.
Day 4 ATC
We arrived at Mumbai, and realised this is a real city. Delhi is prety much an junkyard, with people bothering you all the time trying to get money or sell you something, roads are made of dirt, and cowshit is all around. Taksies rip you off at every corner. Still very cheap even when they overcharge. Here there are actuall streets, big buildings, civilised people and everything you can imagine, of course this results in higher prices.
