The Associated Press has just published a thrilling account of Bush's activities while on vacation. I have edited it for length.

CRAWFORD, Texas -- President Bush charged up ... and down ... landing flat on his back.

While the Democrats were at their convention, working ..., Bush was indulging his new hobby ... [w]ith an Associated Press reporter riding ... him.

Bush ... rides with abandon.

He takes on ... veterans.... He keeps a cramp-inducing pace..., panting hard, emitting low "hrrr, hrrr, hrrr" grunts with each stroke..., his shoulders bobbing up and down.

....[H]is heart rate reaches 168 beats per minute. That's nearly four times his resting rate and in the same range as Lance Armstrong's when the six-time Tour de France winner is ... hard.

"At my age, you're more concerned about the cardiovascular" benefits..., the 58-year-old president said.

His ... is one of the best: a ... rear suspension that soaks up big bumps.... "... really a painful experience for me now."
...

Crashes are routine....

On May 22, he lost traction ..., scraping his chin, upper lip, nose, right hand and both knees.
...

Bush approaches ... warily.
...
"I'm gonna show you a hill that would choke a mule," he says.

He ... is steadily advancing when ... [h]is foot gets stuck in a strap .....

In the blink of an eye, his rear ... is in the air....

He lies motionless for a few moments. The reporter hoists ... him just as his medics arrive to attend to him.
...

Bush straightens out..., throws a leg ... and keeps rolling.
...

Bush loves showing off ..., and he takes his guests -- and the Secret Service agents who ride ... him, pistols bulging through their shirts -- to far-flung areas.

.... He slips at first, saying he will practice....

In one meadow, cattle stare ... at him as he rides ... littered with cow dung.

.... Bush is fiddling with his ... rod when a fellow rider pulls up, and ... says he's just finished....

.... Bush swats away ... his ad man, Mark McKinnon....

When the reporter points..., Bush says, "Who?"

What a man!
