The first 3 photos show the tree being lifted into place. The last 2 show how it looks. It would be a nice spot for a tree like that all the time. But ya can't have a real tree (with roots) there. It is not really the ground. It is a roof of the Borough Hall Subway Station.
So I was in Borough Hall today because I volunteer there on Tuesdays. In the Tourism and Visitors Center, in Historic Borough Hall . Some one came in and asked us when the tree will be lit. Nobody knew. I googled it. This is the site that came up Famplosion: Do stuff together. I wonder how they new and we did not.
