I saw part of your travels Nagaland. Too bad you didn't go to Darjeeling. It is ahill station 5,000 or 6,000 feet high altitude, very similar to Austria in scenic landscape. The sunsets are a sight to see. The sky is full of orange and red huesof of colors. There is a splendidview of the snowy Mt. Kinchinjunga (?), third highest mountain in the world and most beautiful. It is wide and triangular.
