My kids go to catholic school so, no, they don't.
But at most public schools here- it's allowed.

Do your kids go trick or treating after school?

And also, I've seen this in films as well, so it might be wrong, but do American kids tend to leave early. Like, before it gets dark?

It depends on the neighborhood, some paranoid communities think kids will be somehow "at risk" if they go out at night, so they trick-or-treat during the late afternoon.

I'd never trick or treat with my kids until after dark.

our kids have a costume parade at school, but they are encouraged to change into their costume for the parade (at the end of the day) and not wear their costume all day long as it causes quite a classroom distraction.

And yeah, there are quite a few industry families in my kid's school. The prop guys and set-builder dads always help me construct the school's haunted house... which I need to start planning:o

Yeh, that's the way it should be done. I can understand being worried about the kids safety, but the parents should be taking them out themselves if they're quite young. What happened to quality time with the kids?

Trick or treating is town curfewed from 6pm to 8pm. We live in an awesome neighborhood to troop around though and almost all the houses go all out with the decorating and candy.:cool:

Wow, I'm sorry, why?

Cause I live in a tiny, red-neck, small-minded, morons rule, inbred, fucked up beyond belief- town.

I'm planning my escape...shhh:D

That's the hours for my neighborhood too, though on the Friday before Halloween all of the shops will have special Halloween open houses in the afternoon and kids can parade and get free goodies from the shops. It's pretty friggin adorable.

I live in a tiny redneck town as well, but it's run by....mormons.....*shudder*

so they are pretty trustworthy.
