Kalkhoven pleased with the big crowd

Late Sunday morning, Champ Car World Series co-owner Kevin Kalkhoven stopped his scooter to soak in the atmosphere at the Grand Prix of Cleveland. Everywhere he looked, he saw people – happy people.

"It really has come back, hasn't it?" Kalkhoven said of the event.

Three-day attendance for this year's Grand Prix was 151,426, including 65,000-plus on Sunday. It represents a 27 percent increase from last year's 118,853.

Three years ago, three-day attendance was 80,000. It improved to 89,877 in 2005.
