In The Lost and Damned, the Lost MC have a clubhouse in Acter, Alderney. Unlike many Alderney locations, the real life version of this building is not to be found in South Kearny, New Jersey, but rather in the heart of New York City itself.
The building in question is the Hells Angels clubhouse (‘Big Red Machine‘) located at 77 East 3rd Street.
