We were at St Andrews by the sea in New Brunswick; it was sunny and the tide was out. Tish inadvertently left her sunglasses there and when we came back to retrieve them from our visit to St Stephen we witnessed the this dramatic transformation as the tide had come in and the very rocks we were standing on a few hours before were totally submerged. We did find the glasses, and realized that this was the real sight we were supposed to see. It all tied in!
