The first is in front of a house around the corner. I'm not sure whether it was hung to remind the kids that the day was here or if the parents were celebrating the end of summer vacation.
The following three banners were hanging outside classrooms at Vista Grande School, just a couple of blocks away. I think it is safe to say that the teachers are welcoming their new students on their first day back for a new school year.
Having spent my entire pre-retirement professional life on college campuses, the year always started when the new academic year began and not on January 1. So a Happy New Year to all!
