So beloved is the 1939 Greyhound terminal, built in the Art Moderne style and clad in enameled steel panels, that it has been depicted on postcards. Now, four years after it was left vacant, the terminal received new hope in the late summer when leaders from Indiana Landmarks, a nonprofit organization dedicated to historic preservation in the Hoosier state, announced they were raising $1 million to save the property and convert it into their southwest regional office. The proof it can be done? This similar property in Jackson, Miss., now has new life.
