We live in a decent sized town, and every year hundreds of kids come to our small neighborhood from elsewhere. They come because people in our neighborhood give out the better candy, baked goods, etc. Pretty much every house also has extensive Halloween decorations, and several do haunted houses.
The kids in our neighborhood are all pretty well behaved, but we've had issues with kids from outside of the neighborhood being rude, stealing decorations, taking candy from younger kids, etc.
Our neighborhood is 24 houses and we have a HOA that pretty much everyone participates in. Its not some crazy HOA like you might read in some posts. We throw parties, bring people food when they're sick, etc. It's expensive to buy so much candy, I usually do gift baskets, and last year I ran out before all of my neighbors kids could come to my house.
I wanted to make sure all my neighbors' kids got a basket this year, so I made a sign that says "candy only for kids living in the Rosewood Hills neighborhood." That I planned on putting at the end of the driveway. I dont want my neighbors' kids as well as kids from outside of the neighborhood coming to my door, and giving one kid a piece of candy and a different kid a gift basket.
