The arrival of spring in Boston is not complete until Opening Day. By this, I refer not to Fenway Park (for America’s pastime), but to Cruiseport Boston (for my pastime). Tomorrow marks the beginning of the 2013 cruise season in Boston, as Norwegian Cruise Line’s Norwegian Dawn departs on the first of her weekly, seasonal cruises to Bermuda. The attached photo of Norwegian Dawn was taken on Opening Day 2012, and I hope to get to the port tomorrow to capture a new photograph. Welcome home, Norwegian Dawn. And welcome, spring!
