A parade that is its own audience

A few years ago we discovered that there is an annual Halloween parade in front of our house. How we lived here for over twenty years before finding out about a annual parade with hundreds people in it is sort of mysterious.

Also mysterious is who organizes the parade and where they go afterwards. Here's what we know: there are a few signs around the neighborhood announcing when it will happen. It has nothing to do with trick or treating. They walk the length of the park we live on and then they go somewhere else. We don't know where.
   There is virtually no gathering of an audience. How can we gather if there is no publicity? I guess that's not the point: it's for the fun of getting dressed up and walking in a big group. Somewhere. Some year I will find out when it is, get in costume, and walk along to see what happens. There are a lot of very small children with parents but there are some unaccompanied adults as well.
   Again this year we happened to see the parade just by accident. I liked the accordianistas that had a Day of the Dead vibe going. (For the most part, the parade is very quiet.)

 Here's a family of bees attended by their bee keeper. I'm not sure why he has maracas.
