India Is Big

India is big in population, area, variety.....
My first hours of my only visit to India were spent lost on streets on the outskirts of Bombay. In a matter of hours I escaped to Sri Lanka. I enjoyed Sri Lanka.

I'll need a lot of help to make a pleasant stay in India.

My ignorance of the country is my biggest problem. I have thought to start by trying to research some cities smaller than Cennai/Madras.

For luck I've selected seven more or less at random:
Thirovagoor, Madurai, Lucknoow, Thanjavur, Jamshedpur, Vijayangara, Chandigarth.
I'd like to find a comfortable city with great air quality.
