I don't think our traditions are unusual, but we have a lot going on in October. Lots of area corn mazes and commercial haunted attractions. The weekend closest to Halloween, the city parks & rec puts on a Halloween bash in one of the larger parks. There is a carnival for grade school kids, and there are haunted hay rides. One of those is not scary, for the little ones, while the primary one is as scary as they can make it. They also have costume contests.
On Halloween night itself there is lots going on in the neighborhoods. One street near us is so highly decorated that people drive in to it and park their cars. Our street gets some spill-over from those folks. Another prime TOT area is the historic district downtown, where many of the oldest and wealthiest homes put on quite a show.
When my kids were in grade school, they always had a book character parade at Halloween. It wasn't called Halloween, but was supposed to encourage reading. They were quite flexible, though. Little boys dressed as Spiderman could carry comic books. My daughter, dressed as a witch, could carry Harry Potter even if she didn't look like any of the characters in HP. And the teachers and administrators would costume as well, only theirs really would be from some recognizable story book or fairy tale.
The second graders would generally have a field trip to a pumpkin patch.
There is one non-denominational mega-church in town that has a blow-out "harvest festival." They won't do anything spooky, but they have many seasonal activities and are well attended. Other churches. including ours, have Trunk-or-Treat. I support that as long as it doesn't supplant the street masquerade, which so far it has not done.
