Editor’s Note: Some stories just have to be written down. Such is the case with Edo Potter’s story of life at Pimpneymouse Farm on Chappaquiddick that began for her nearly 80 years ago at the age of four, and continues today. The Last Farm on Chappaquiddick is at once a memoir, history book and chronicle of a changing island. Written by Mrs. Potter and published by Vineyard Stories, the book will be on sale at Edgartown Books, Bunch of Grapes, in Island stores and through the Vineyard Stories Web site (vineyardstories.com).
