It will be a perfect night for hunting down the best candy on the street. We'll also be going to church, well, at least my wife will be. My daughter just had a major meltdown after saying the paint job my wife did on her looked stupid. She said this 3 times and got her faced washed off. Now trick or treating for her is in jeopardy.
Costumes: I do not like masks that cover faces. To me that's the easy way out. I prefer students to have faces painted or extra hair and appropriate clothing to match the theme.
Candy: I have no problem handing out the cheap, small stuff: Tootsie Rolls, Gum, DumDums, etc. I enjoy pilfering through the candy that my kids get and picking out the good stuff. I'm not big on sweets so I really only take the GOOD stuff.
Time: I think allowing the kids to go out about 30 minutes before it gets dark is okay. I mentally have an 8:00-8:30 cutoff for going door to door. No kid trick or treat age should be out past that time anyway. All of those after 8:30 are teenage delinquents.
Lights out: When the time is right I turn out all the lights and move everything to the back room.
Parties: I've never really gotten into adult Halloween parties. Maybe it is the group of friends that I grew up with who weren't really much into partying. I think I went to ONE bar Halloween Party in my life.
November 1st is a good day to be going to a Catholic school. All Saints Day means NO SCHOOL!
