Recently, I made my fourth trip to Panama.  Each trip, a short visit to the Canal in one form or another, gets included in the itinerary.  To understate the importance of the Canal to Panama and the World from an economic point of view is not possible.  The Canal gives Panama money to do things many other countries in Latin America – especially in Central America – can only dream about.  Large freeways, light rail, subways, and a seemingly burgeoning economy from a casual tourist outlook reflect success in the heat, humidity, and constant drip – or sudden deluge – from the skies here in Panama. One factor hiding from plain sight today are the former huge efforts made in defense of the Canal.
