No trick-or-treaters? Buy candy anyway!

Don Stewart and his wife will be home with the lights on Halloween night, waiting for trick-or-treaters. But like a lot of folks who stock up on candy, they'll probably end up eating it themselves.

"My wife and I buy candy every year, knowing that trick-or-treaters won't come to see us," says Stewart, an artist in Homewood, Alabama.

That's why they buy the treats they like, not necessarily what they think kids will like: "Nothing is wasted. If we plan well, there's usually enough to last us until Christmas."
