An autograph session featuring some of the world's top professional bodyboarders runs from noon to 2 p.m. tomorrow at Ala Moana's Center Stage. The event, called Go Big!, kicks off the 2007 Rockstar Games Pipeline Pro and includes giveaways of bodyboards, fins, leashes, board bags and other prizes. It's free.

There are games, too, in which contestants will be called to the stage to compete in events such as Stack the Wax, Towel Changing and Lifesavers Challenge.

The pros scheduled to appear include Mike Stewart, Jeff Hubbard, Toby Player, Damien King, Jason Bitzer, Ryan Hardy, Robert Bitzer, Michael Novy, Mitch Rawlins, Alex Bunting, Andrew Lester and Ben Player.

An after-party follows at the Mai Tai Bar. www.TCSurf.com.
