In 2010, a children’s garden was dedicated to the memory of Cindy O’Hanley, a cherished volunteer Nature Guide and leader of Teatown’s Little Tree Huggers and Knee Hi Nature groups. “Mrs. O” shared her love of nature and, especially, plants with many budding naturalists. By 2018, the wood used to build the raised beds and the bench were succumbing to rot.
