First Lady Heads Out of Town After Speech in Alpharetta

First lady Michelle Obama has left Alpharetta after giving a speech on childhood obesity prevention to paretns at North Point Community Church. She left the city at about 5 p.m.

Traffic on Old Milton Parkway and North Point Parkway was backed up for a half hour before her departure as Alpharetta Police selectively allowed lanes to clear onto streets not part of her route out of town.

There's one way to get through bumper-to-bumper traffic on GA 400, and that's a rolling roadblock. First lady Michelle Obama's security team used one to get from Atlanta to Alpharetta, and heading back out of town.

For anyone who didn't know why traffic was stopped at intersections and ramps along her route, it had to be frustrating.

Her speech on what parents can do to help fight childhood obesity was streamed live online on the Let's Move Web site.
