When I shifted to Pune about 11 years back, the winter mornings used to be super crisp and clear. The clearer the sky the colder the night - Percy's mama used to say. Over the last 4-5 years the Pune winters have been reduced to a week or two. The days are full of a white haze (smog mostly). So when rarely a day opens up crisp and clear, it is a joy to be outdoors.
