I didn't let my kids trick or treat for years because of the religious thing, but I came to the same conclusion you did, ceecee. If we can do church parties, what's the difference? So I started taking them trick or treating several years ago. I'm so glad I did. I feel really stupid for not doing it sooner, but hindsight and all that.
Our youngest is eleven this year, my fifteen year old is never going to make it to five feet tall, and my thirteen year old is just over five feet (and growing fast) so those three can go to the door. My 5'8" seventeen year old and I will wait on the sidewalk and then she will mug them of their booty like a good big sister.
Don't know what we'll be doing next year.
