RORY: Yeah, but … it’s all the way in Boston.
LORELAI: I’ll drive you there if you want … Yeah, I’ll do some Boston shopping …
Boston is about two hours drive from the location of Stars Hollow, which is a significant journey, but never made to seem like a big deal in this episode. Lorelai and Rory would have spent four hours getting to and from a baby shower, but Lorelai makes it sound like a fun shopping trip. Mind you, this is the woman who drove to New York to go shopping, and drove home again without getting out of the car.
