Treehouses in mid-town

"Tree Huts" Installation in Madison Square -
Tadashi Kawamata, artist

This was rather thrilling to come upon, the presence of treehouses in mid-town Manhattan being very unusual. Had the homeless people found alternative solutions? I recalled the book Missing Angel Juan by Francesca Lia Block where the young Juan lives in the trees of Central Park. I sat on a bench for a time, observing interactions with the work. There are about eight huts in all, indeed out of human reach, but likely not for the squirrels and birds.
