Dirty Linen Night is on Saturday, and the second Saturday of the month also brings art gallery openings in the St. Claude Avenue corridor. Barrister's Gallery opens a photography show titled "Los Invisibles: Latino Immigrants Who Rebuilt New Orleans." It includes the Craig Morse photo above, "Carousel of Democracy." Other downtown galleries opening new shows include Good Children and The Front. In the French Quarter, galleries and stores on Royal Street open from 6 p.m. to 10 p.m. for Dirty Linen Night.
