I think it's too late to write this entry, but I visited Portland and Boothbay Harbor, Maine in this September. I watched a musical play Carousel at Kokugakuin Tochigi High School performed by its musical club a few weeks before. Carousel is a musical that features a love story of a young girl and a barker in Maine, filmed in 1956. That inspired me to visit this state and, if I could, eat some lobsters and clambakes.
There were no direct flights from Tokyo to Maine, so I chose flights from Tokyo (Narita) to New York (JFK), and from LaGuardia to Portland (Maine's largest city). All flights were Delta Airlines.
