Trick or TreatNext Wednesday is Halloween and I do expect kids and adults to trick o' treat my block. Talking with neighbors, we expect the bands of costumed and uncostumed to come by between dusk and 8ish-9ish. Despite the groups of kids who don't make an effort, giving away candy is fun, doing it keeps the tradition alive, and kids 5 and younger in costume are sooooo cute.
Frozen Tropics has a pretty good tips to doing Halloween in the 'hood. The only thing I would have to add is I ration the candy. I buy cheap candy that I give to people who don't try or who are not the target audience. That's my punishment for them. Kids in costume get the good stuff. It may seem to some unfair, but hey, everybody gets candy.
