We have two daughters, now aged 14 and 12. This year the 14 year old opted out, so I took out the 12 year old while my wife and oldest stayed home.
We have an active neighborhood, but we live on a cul-de-sac which veers uphill from the main area. My wife said only 12 kids made it up there.
Those of us that did go out noted that the neighborhood traffic was down quite a bit this year, but still plenty healthy. All the parking at the community park was full with imported trick-or-treaters, so at least we are still a place that people want to go.
