MIAMI (AP) - First lady Michelle Obama is celebrating the fourth anniversary of her "Let's Move!" youth health initiative by hitting the road. Her next move: head to Miami.
    
Obama plans to visit local parks and recreation centers Tuesday afternoon to talk about ways to help children get involved with healthy activities out of school.
    
Obama launched the "Let's Move!" program in February 2010 to promote a more active and health lifestyle in a nation where obesity has become an increasing problem.
