I think about swimming with him into the cave at Portuguese Bend, about the swell of clear water, the way it changed, the swiftness and power it gained as it narrowed through the rocks at the base of the point. The tide had to be just right. We had to be in the water at the very moment the tide was right. We could only have done this a half dozen times at most during the two years we lived there but it is what I remember. Each time we did it I was afraid of missing the swell, hanging back, timing it wrong. John never was. You had to feel the swell change. You had to go with the change. He told me that. No eye is on the sparrow but he did tell me that.
