First Lady Michelle Obama is promoting walking to school as part of her anti-obesity campaign.

In remarks to mayors gathered at the White House last week, the first lady singled out Knox County, Tenn., which – inspired by Mrs. Obama’s “Let’s Move!” campaign — has created a bike-share program and something called a “walking school bus.”

“I’ve heard more and more of this kind of walking school bus happening all over the country — so that kids can get exercise on the way to school, kind of like we did when we were growing up,” she said.

A “walking school bus” is a group of children who walk to school with adult chaperones.
