This morning, schools across the D.C. Metro area are participating in International Walk to School Day.
Dozens of schools across the area have planned events to highlight the benefits of walking to school.
The nation's secretary of transportation, Ray LaHood, will join children, teachers and parents walking to East Silver Spring Elementary later this morning, along with Maryland's Lieutenant Governor, Anthony Brown, and Montgomery County Executive Ike Leggett.
Leggett says while health and environmental concerns are an important reason to walk to school, the biggest obstacle can be the distribution of schools across a community.
"The biggest obstacle, certainly, is financial, because you have to have enough schools so they are not so far apart that it discourages walking," says Leggett.
East Silver Spring was the first Montgomery County school to hold a walk to school day celebration back in 1999.
