Last week I visited agra as a part of faculty tour. Few things which I noticed very common over there was people looting the tourists, doesn't matter whether its indian tourist or forrigners. They ask for thrice or four times and even more price if they see some new tourists. It was te case not only at tajmahal only but also at public places like railway station, bus stands etc.
Second thing is that the city is very much polluted. I still remember when we were in train and asking each other how much time would it take to reach agra. Then one of us told that the moment when you will be unable to breathe without keeping a hanky on your mouth, understand its AGRA. And the same happened.
Of course the tajmahal was best. We captured good memories. The sweets like pethas were awesome but what remained in our memory is the dirtiness over the city and people looting the tourists.
