RORY: Now, to the best of my map reading abilities, we’re headed towards Portsmouth, New Hampshire.
Portsmouth is a city in New Hampshire, a historic seaport with a strong naval tradition and a population of around 20 000. It is a popular tourist destination during the summer months.
Portsmouth is around three hours drive from the area where Stars Hollow seems to be located. As Lorelai has been on the road for at least six hours, quite possibly longer, they must have taken a very roundabout route.
