Haha my wife & I were crushed when our daughter got too big for trick or treating because it meant we couldn't go any more either... just too weird if there's no kid tagging along lol.
We don't have kids, and since we moved to the country, we miss giving out candy. My wife's great uncle live in town, so we give candy out there. There is a ton of kids that come from all over the county that show up.
