We do the walk, regardless of weather. We are a one-van family and my husband uses it for the commute. I will be walking children to school for a few years yet, and truthfully, I enjoy the walk. I do it with another local provider and we really enjoy ourselves. It also makes it easier if the stroller gets a flat tire, or we need help getting over snow drifts, ect. We help each other out that way.
Pushing all those kids keeps me trim. LOL!
