I need to look back for it but I thought they were driven because being the first on the bus made for a long ride but that they ride the bus home because they were the first off.....
Not positive...Could be mistaken, but I believe Verified Insider Jilllian may have posted that children took the bus home that day.
If I find post, I'll link.
ETA: Nope cannot find a post. Jill, any idea whether children took bus home that day?
