WASHINGTON -- Michelle Obama is marking the second anniversary of her "Let's Move" campaign against childhood obesity.
The First Lady has planned a three-day national tour beginning Thursday.
Her first stop is an arena in Des Moines, Iowa, where more than 10,000 children will do some physical activity.
From there, she will travel to Arkansas, Texas and Florida before ending at Disney World in Orlando, where Disney stars, athletes and local kids will all come together to get moving.
Along the way, Mrs. Obama will highlight roles that churches, restaurants, schools, businesses, families and the military can play in fighting obesity.
The First Lady's goal is to solve the problem of childhood obesity within a generation.
