Portland

Portland was a city on Earth.

In the mid-20th century, people, even those in rural areas, could hear about what was happening in this city on the radio. Though people might feel they were far from events, radio brought them in closer. 

Benjamin Sisko's sister, Judith, resided in this city in the late 24th century. 

In 2372, Joseph Sisko told Judith to return home to Portland, as he felt he did not need her to help in the family restaurant.
