The newest theme is the autumn colours. It is of particular interest to me because we do not have the total deciduous tree landscape that they have, so we don't get the amount of colour.
I arrived in early October and the leaves in Central Park were mostly green with some colour starting to show.
And by the time I left, autumn was well and truly showing. In fact, winter seemed to be approaching - if you looked at the plants. But look at the people and you can see that it was unseasonably warm! Not that I was complaining!!
