SANTA CRUZ, CALIFORNIA

If everybody had an ocean across the U.S.A., Marisa Miller would be very happy. "Surfing's the best exercise in the world," says Miller, who lives a few steps from the beach in Marina del Rey, Calif.

She was surfing two years ago when famed photographer Mario Testino took pictures of her; the 23-year-old has since done ads for Tommy Hilfiger, and has been on the cover of Shape.

This is her second appearance in the Swimsuit Issue, but she's no stranger to sports. She grew up a 49ers fan and snared Jerry Rice's signature at a mall when she was in eighth grade. "I tore off a piece of my shopping bag so he could sign it," she says. "I still have the autograph."
