For centuries castles were considered the high points of their communities. Join Rick as he talks castles with an expert guide from Wales and offers recommendations for which sites travelers to visit -- from historical ruins to converted B&Bs, all the way to Transylvania. Next, Rick learns about American high school students who travel to Guatemala each summer in order to learn first-hand how connected we really are in our modern world.
