Mayor Luke Ravenstahl today told Pittsburghers they've "gotta believe" during an inauguration speech tonight that was more pep talk than vision statement.

Ravenstahl, a Democrat, won a Nov. 6 special election against Republican Mark DeSantis and will serve out the last two years of the term won by Mr. O'Connor in 2005.

Ravenstahl, 27, holds the distinction of being the youngest mayor of any major U.S. city.
