This one, a block from home, presiding over the cab route on Clinton (I consider myself to be blessed to be near this arterial stream of cabs, so rare in Brooklyn, returning to the heart of Manhattan), anyway - this tree reminds me of the round green things on brown trunks that I drew as a child. A tree kind of a tree.
