I'm Lutheran (Protestant) and we never do stuff on Wednesdays either. If you can't or don't want to go to church on Sunday morning, there are services on Saturday night. Most of the other churches where I live do that too -- and I'm in Kansas, there are a LOT of churches here. There's pretty much a church on every major street corner of all different denominations. No holiday has ever been moved due to church happenings.
Some of the posters report ToT'ing on the Thursday before, no matter what day Halloween falls on. What is the reason for this? I just think it's so weird that a holiday would arbitrarily be moved around, and it's different from one town to another. Do they move other holidays around too? Why Halloween and not Christmas? And how does the town alert people? What about those who don't have kids and just like to hand out candy, or whose kids are yet not school age? Obviously they won't be bringing flyers home from school. What about people like me, who don't get a paper and rarely watch the local news? I would be surprised as all get-out to have costumed kids on my porch a full week before Halloween, I'd be thinking there's something wrong with them! Or more likely, I wouldn't be home and then I'd send my kids out a week too "late" on real Halloween, and then what?
BTW helenabear -- I just love that little baby animation in your signature. I've been mesmerized by watching it for the past 5 minutes!
