For Episode XVI we return to Mexico but this time to explore two vastly different geographical regions of this rich and beautiful country.  Our first stop is the Yucatán Peninsula.  Here we will explore the jungle landscape of the Mayan Empire and visit one of the greatest wonders of the ancient world.   It was here that the great asteroid struck millions of years ago causing the cataclysm that wiped out the dinosaurs.   Then we move on to the tip of the Baja Peninsula.  This is a desert landscape surrounded on three sides by crystal-clear vibrant blue waters teeming with marine life.   And, just maybe, we will will have the chance to swim with the largest fish in the world
