HOUSTON --Houston has been chosen as the processing site for U.S. athletes competing in the Pan American Games in Guadalajara, Mexico, in October and the ParaPan American Games in November. U.S. Olympic Committee CEO Scott Blackmun said Thursday that more than 1,700 athletes and coaches will stop in Houston to get their uniforms and meet each other before flying to Mexico. Blackmun says most members of the team will spend 24 to 36 hours here. Houston Sports Authority Executive Director Janis Schmees said some of the athletes also will train in Houston and offer public exhibitions of their sports before the games. Blackmun says Houston was chosen because it is close to Guadalajara (about 1,000 miles), has the hotel capacity and is a hub of United Airlines, which recently merged with Houston-based Continental.
