Years ago, 1997 to be precise, my husband and I rented a tiny cottage for 2 weeks in Canada, on Campobello Island. The island is best known for playing host to the Roosevelts. Specifically Franklin and Eleanor. On the eastern shore of the island, there is a picturesque little beach called Herring Cove. It was here that, in 1921, after swimming in the icy sea, FDR was (erroneously) thought to have contracted the polio virus. Cold water and presidents aside, what Herring Cove should really be known for, is its rocks. The fine specimens pictured above were all collected at the beach. Something about the tides and the geographic location of the inlet tumbles the rocks to a softness that seems nearly impossible.
