Riding Dirty - Celebrities 'Learn to Ride' Motocross With Oakley Star Riders

Oakley's roots are in motocross.

And our celebrity friends
learned this fact...the hard way...last month as the Big O's rockin'
'Learn to Ride' program took a few on a crash course on dirt bikes.

The
program -- which teaches celebrities a thing or two about an action
sport -- brought some of Hollywood's hottest young stars out to meet O
Motocross Stars like top Supercross/AMA Motocross Championship rider
Davi Millsaps in the Southern California desert (Lake Perris). But make
no mistake, this wasn't just any meet and greet.

The stars got
down and dirty -- gearing up in Oakley Motocross gear, mounting dirt
bikes and trying their luck at the intense sport.
