Does anyone have any unusual or "strange" customs that are specific to their city or village they live in?

In my town, every year we gather in city hall to make pic related. These are called Gummys. Its a custom that goes back almost 100 years. I come from a poor state in the US (wont say which one) that until recently had very few jobs. The only real industry here was candy and many families worked for a gum factory here to make ends meet. On christmas many families would make gummys as presents for one another because nonone could afford toys. I didnt realize it was unusual until I started traveling around 20 and no one knew what I was asking about when I talked about making gummys.
