I grew up in Ohio and it was always on Oct 31. I moved to NC 10 years ago. One year the town did try to change it when it was on Sunday and there were protests of them trying to change it. Of course some of the really religious people then protested it being on Sunday. (It ended up being on Sunday.) And the new city I'm living in is having it on Sunday. Personally I don't care, just would like to be informed so I know when to have candy around in case anyone shows up. Since we moved I have no clue how many, or even if we'll get any kids. Plus this is a military city and people are always moving in and out of the neighborhood.
