@ Bschloop. Unless one of your goals is to shock the top contenders when you show up with this possible winning bike, you may want to let Kraig know you're coming and send him a picture to his email. He'll probably give you a chance for an interview and include you as part of the promotion of the event if he knows you're coming. He'll also add you to his list of ICE-powered entries over on his website that highlights the upcoming event.
Like Sendler says; no registration is required, but if you want a little more attention for your efforts, you can let him know in advance at the following link and click "contact" with the subheading "share ideas"; he's also got a phone number on there if you'd rather call him.

On a related note, Kraig says that a motion picture crew will be traveling with Craig Vetter and that we should all have our bikes looking good and be prepared to possibly be in part of a movie being made about Craig's life.
