President George W. Bush had his mountain bike.
President Barack Obama has his basketball.
The former president would slip out of the White House on a Saturday morning, if slipping entails a high-speed motorcade, and head for the woods.
This morning, on a cold and overcast day in Washington, the president and friend Marty Nesbitt (pictured here), wearing sweat suits, climbed into the presidential SUV at the White House for a short ride around the Ellipse in a slow-speed motorcade to the Department of Interior.

Obama aide Reggie Love, riding in another SUV, carried the first basketball.
“Who knew they had a basketball court?” the Dallas Morning News’ Todd Gillman, performing Saturday pool duty, wrote of the trip.
Like the former president’s weekly bike rides, which were performed out of eyesight of the pool reporters, the president’s game on the court at Interior was played in private. The outing ran a little under two hours.
It might have been a rough game: Nesbitt, who had joined the president in taking in a game of the Bulls and Wizards the night before at the Verizon Center, wore a brace on his right leg and walked with a limp as they returned to the White House.
Press aide Ben Finkenbinder’s T-shirt was darkened with sweat from his first basketball game with the boss, and played the event like a dutiful press aide would: No details on the players, score or highlights of the game.
