RINGLING RETURNS: After a four-year absence, the Ringling Bros. and Barnum & Bailey Circus returns this week to the Baltimore Arena. Shows are scheduled Thursday through Sunday, this week and next -- 21 performances in all.
But if you just can't wait for the opening performances at 4 p.m. and 8 p.m. Thursday to see a little circus action, you can at least see a few of the animals and perhaps some clowns as the menagerie takes a stroll to the Arena about 6 p.m. Tuesday from a rail siding near Pratt and Arlington streets. A mayoral "welcoming ceremony" featuring a couple of elephants, clowns and showgirls is scheduled for noon Wednesday at City Hall Plaza. Show information: 347-2000.
