Trick or treating, definitely! I'm all for the scary Halloween, too. My mom can get cutesy little witches or whatever (we have a lot of witches, as she's Pagan) but they don't go up ON THE DAY. Oh no. I've taken over Halloween as my holiday, and Mom can do whatever she wants with the other holidays. I go all out decorating our front step. If we had a front yard, I'd do even more. I'm just dying to build a full-on haunted house, but our back yard is nearly inaccessible (trick-or-treaters never go back that way) and the condo board gets all persnickety about people setting up decorations on the common grounds. This year, I'm thinking screw them, I just set my stuff up for the one evening, and take it down before I go to bed.
We don't get a lot of kids, either, but then we're four blocks from a major mall and our front door is hidden. But the kids who do come love our door every year. Best reaction ever was a little four-year-old boy, standing on my meowing black cat doormat, holding his candy bag close to his chest, and just shaking like a leaf. He was so cute. His mom was at the bottom of our steps, laughing. She told me that the year before, he was too scared to come up to my door! I gave him extra candy for being so brave.
When I was growing up, we did both the trick-or-treating and the mall thing. We usually went around our neighbourhood first, when it was still a little warmer, and then headed to the mall when it got cold. The best part of the mall trick-or-treating was that we could run around without jackets and mitts and show off our costumes. But the awesome candy hauls always came from the neighbourhood houses.
