This is great news — I will not be able to be there; I will probably still be on my way in after accompanying my son and his friend to school by bike that day.
By the way, a number of Fairfax County Public Schools are participating in Bike to School Day. You can check at the link to see if your school is participating, and if not, you can register it yourself. The following week (May 14-18), Vienna area elementary schools will be holding the Vienna Walk and Bike to School Challenge. Each school will tally the number of students walking and biking each day that week and the results will be published in the Vienna Patch.
Be sure to join the fun if you have a youngster in Fairfax County and Vienna, specifically.

EDIT: Bike to School Day is a national event — you don’t have to be in Fairfax County to participate. I just don’t know what other jurisdictions are doing to promote the event.
