The WNEW/New York afternoon talkers and Westwood One syndicated personalities are off at least through the end of this week after news broke of their contest encouraging couples to have sex in the city's riskiest places; the couple who had their encounter in St. Patrick's Cathedral - just feet from worshippers - were even arrested. At press time, officials at Westwood One were unable to confirm if Opie & Anthony's time off was scheduled or an enforced vacation.
