For many people, summers are spent building forts and castles on the shores of oceans and lakes, or burying a patient parent up to the neck. And then there are the true sand artists, who create soaring, monumental sculptures out of the famously ephemeral substance. They work for hours creating detailed pieces with the full knowledge that they will, in a short time, crumble back into the natural shoreline. One such artist is Carl Jara, who has been creating these sculptures for 20 years, and loves every moment of it.
