One of the holiday displays for First Wednesday Art Walk was a decorated tree near the Skyway station at Hemming Plaza. Mayor Alvin Brown will light the tree at 7 p.m. Friday during “Holiday at St. James.” The city-sponsored event begins at 4:30 p.m. in the plaza with train rides, face painting, cookie decorating and a screening of the film “A Christmas Story.” Tours of City Hall, including the City Council chamber and Brown’s office, also will be available.
