For many years my husband took me, in his Scout boat named "Shrimp & Grits" to our favorite islands off of the coast with my BIG easel and backpack to paint the high tides. The tides would flood the interior and bring in the fish. I'd wade through the water and set up behind high dunes and watch the water rise and color the normally dry looking island. Many of these marsh paintings are painted on the very same location.
