When you are doing the main task of "Weird Valentine", that is, after the Valentin Detective Office in Diamond City receives the task of finding Nick Valentine, this task will require you to go to the location of the Boston Metro South Station. To find the park, there is a large circular open space on the right side of the subway station entrance, with a stone pavilion and a pond inside. This is Boston Park.

Then there is a statue right in front of the entrance to Boston Park. The manhole cover under the statue and a path paved with red Shi Zhuan are the starting points of the "Road to Freedom". Along this road, you can find the railway organization in the old North Church and the basement of the church.
