Walk & Roll to School Day is a great way to help get kids on the move and out of the car!
The upside: there may be fewer cars on the road in the morning, and more students on foot and on bikes. You may see large flocks of them traveling together.
The downside: Some families may not be used to riding bikes or walking to school - if they don't give themselves enough time, they'll be in a hurry. And of course, if it's your commute time, you'll be in a hurry too. So, for safety's sake, please be extra-aware between 7:30 and 8:20, so that everyone gets where they're going on time and happy!
