The Blue Horizon was a ballroom built in 1914 for the Loyal Order of Moose as an attachment to a set of row houses from 1865. The venue was used for boxing from 1938 to 2010. It was used for fight scenes in the films Rocky V and Annapolis. When I visited, plans were in the works to demolish the facility and replace it with a parking garage.
Work is of two kinds: first altering the position of matter at or near the earth's surface relative to other matter; second, telling other people to do so. (Bertrand Russell)
