About 75,000 people are expected to be in Invesco Field tonight for Barack Obama's historic acceptance speech, and a good number of them will be part of the massive security force here.

Photojournalist Chad Flowers and I spent two hours trying to make it into the stadium from the CBS News compound nearby. Inside, law enforcement officers with binoculars and high-powered weapons ringed the top of the stadium, scanning for potential trouble.

Secret Service, FBI and officers from agencies in every Colorado county have been in Denver all week, but they were never more visible that for the final night of the convention. They've been preparing for this for 13 months, and it appears they're ready to head off any problems.

Covering a national political convention is not all fancy receptions, rubbing elbows with the bigwigs and seeing people in crazy costumes.

There is some work involved here, and David Crabtree and I do much of our daily duties in a trailer outside the Pepsi Center, where we share quarters with other news organizations.

You never know who you'll run into on the floor of the Democratic National Convention. It might be a football immortal, or a 1980s TV actress or the former secretary of state. Even the star of the "Harold and Kumar" movies, an ardent Democratic activist.

The Associated Press reports that Kal Penn, aka "Kumar," is the floor manager for the Virginia delegation at the convention.

Several yards away was Franco Harris, the legendary Pittsburgh Steelers running back whose legs and moves carried his team to four Super Bowl championships between 1975 and 1980. He was standing with the Pennsylvania delegation – towering above it, actually – and said he finds many parallels between professional football and big-time politics.

"Sports, politics, there is a big connection there," Harris said. "It's about developing the skills and developing the intellect. And it teaches you how to be competitive."

Barack Obama put the finishing touches on his acceptance speech for the Democratic presidential nomination, but he also found time Thursday morning to shoot some hoops on a basketball court at the Denver Athletic Club.

Obama waved to supporters as he came out, wearing a Secret Service cap, a brown shirt and athletic pants, The Associated Press reported.

Campaign spokesman Dan Pfeiffer said Obama also was doing some final work on his speech.

"Doing the speech at Mile High (Stadium) is an important point for our campaign. It's symbolic of how Sen. Obama won the nomination. It will show how Obama wants to involve people who are not usually involved in the political process," Pfeiffer told reporters.
