Next up on Mayor Rudolph Giuliani's clean-up-the-Big-Apple agenda: potholes.

The mayor, who's cracked down on everything from jaywalkers to strip joints, doesn't like to draw attention to the city's blemishes. But even he conceded New York's large potholes are a "perennial issue."Officials vowed Wednesday to fill about 25,000 over 11 weeks - by the city's estimate every pothole in New York.
