Back to Barrier Island. Everyone knows that if you want to keep a bay or harbor safe from the ocean waves and currents it's VERY important that there be a barrier. A reef or an island. Sea Castle has it's own barrier island! "Well who cares, Hoot?" you might ask. I care and the point is that more thought went into this one painting then went into the entire "Mission Space" attraction! One background painting, folks. It has more research and detail and it reflects old school Disney pure and true.
