From the Writer's Almanac:
When St. Patrick's Day is on a Friday, certain bishops grant a release from the traditional Lent Friday no-meat observance. This release is called the "corned-beef indult."
When I lived in Chicago, back in the late 60s & early 70s, they dyed the Chicago River green on St. P's Day; I expect they still do. Green was everywhere, as were drunks. The celebration for San Giuseppe, St. Joseph's Day, follows on March 19. Joseph is the patron saint of Italy. One should properly wear red for Beppe's day. The Italian guys at the Tribune were always grouchy about the attention given to the Irish patron. The food for San Giuseppe is much superior to that for St. Patrick.
Art for Paddy's Day, a stream in County Sligo ... Small wonder that the Irish of the diaspora held memories of home as the most beautiful place in the world.
