Pioneer Village is a place that you can go for a slice of history. They have old houses from long ago and many host mannequin's dressed up how people lived then, they even have an old schoolhouse and much more.
Every year, Pioneer Village has a Safe Halloween for two nights. This year they are having it on 10/28 & 10/29, which I believe falls on a weekend. The cost is $8.00 per person and they have over 30 local sponsors that have decorated certain areas and houses of Pioneer Village and they hand out treats. I've taken my two oldest kids once so far and want to take them again this year. Lots of people go and it's interesting to see all the kids and their costumes.
One word of advice is to take a flashlight because when it gets dark, it isn't that well lit in some areas.
