Coonoor is a picture postcard town not far from Bangalore. With its tea gardens, the Nilgiri Mountain Railways and the salubrious climate, it is the sort of place I could see myself settling at. Of course, I am not the first one to have thought of that. The British established a major retreat here. The Army has a large cantonment here. And the horticulture department takes full advantage of the climate to grow exotic trees.
