 Beautiful morning for a paddle. The tides come in, and a really happy professor is going out to see who's running around in the salt marsh at the Knosset Marsh at East Ham on Cape Cod. This is a place for birding. This is a place for shelling. These sandpipers are out getting breakfast. Salt marshes are remarkably productive places. They are the nurseries of the fish and the shellfish. They're the nurseries of the ocean. They too need care. The outer beach is coming in as the ocean rises, but the inner side is often hardened by humans and not allowed to move. And if we're not careful, we won't have the nurseries.
