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.
