Previewing the DNC Finale

In Denver this afternoon, the crowd is building at Invesco/Mile High stadium. That's where the Denver Broncos play football.

But tonight, it's where the Democratic National Convention comes to a close with a speech by the Party's nominee, Barack Obama.

WBUR's Bob Oakes is at the stadium as final preparations are underway and joins WBUR's Delores Handy to give us a preview.
