GUADALAJARA, Mexico — Colombian inline skaters Pedro Causil and Yersy Puello pretty much have only one use for ice: chilling drinks.

Skating on it isn't really an option.

On the other hand, ice could be the future for Keith Carroll, an American who is making the transition from inline skating to short-track speedskating.

Carroll, who failed to win a medal on wheels in the Pan American Games but has big Olympic dreams, says "the way I look at it, the Olympics are something that is attainable."

Causil and Puello don't have such hopes.
