Right now in the Princeton, NJ area it's the start of winter. The last few days the temperatures have been below freezing. Princeton and the neighboring towns are small and mostly rural. Even during the summer there are few people milling around unless there is a festival. When the temperature drops this low very few want to be outside. Brr!
The animals are either hibernating or have migrated south to warmer weather. I saw no birds in the sky yesterday and nearby Carnegie Lake has started to freeze over. The insects and small animals are doing whatever insects and small animals do in this cold weather. They are staying out of sight.
I browsed through my catalog of images looking for something that fit the definition of swarm but came up empty-handed.
So today's image does not exist. Enjoy nothing.
