well u see that by 100 sq.km ,,i meant the whole lahore,,u can make it 500sq.km,,,but the thing is there is huge difference between lahore and other cities thats why people from small cities are moving towards lahore,,,i also live in lahore ,,but my work place is in pindi,,i go to lahore once a month and believe me i am amazed to see the traffic rush and number of cars on roads,,,,,,the major factor behind this is the movement of people from smaller to big cities,,,,,,,development can not be gauged by watching defence,Gulberg,,,i know they are very very beautiful,,but what about Moghulpura,Badami bagh,,Islampura,,etc?????the point which i wana make is that DIFFERNCE between the standards of people and cities is increasing which is alrming for any country.
