Our town has a christmas sail pass. People decorate their boats with Lights, Figurines..etc and usually in the first week, they'll have one night where they sail up and down the harbour. It was one of my favourite things to watch as a child at Christmas time!
Now a couple things we used to have, but have since stopped were
Choirs from the elementary schools would go to our mall and sing christmas songs in the centre court
There was a house out towards the country that would decorate their house from top to bottom with wooden figurines, lights, music.. all the good stuff, and sometimes they'd have santa come out and take pics with all the kids that would come by... I can't remember why.. but im fairly certain it was for their grandchild.
