We live on a street with 29 houses. In the 15 years we've lived here, the costume-count has gone from under 50 to (last year's count) nearly 400. You read that right, 400. The neighbor up the street counts every year, then posts the total on Facebook.
I used to recognize practically every kid who came to the door; now, not so much. Over the years the people in the rural area of CT have found out that they can get away with parking at the shopping area a little over half a mile from our house, then troll the entire neighborhood of houses that are 60 (old section) to 100 feet apart. Sidewalks, too. So much safer than walking the state route in front of their houses with no sidewalks and houses 200 or further apart.
When Himself bought candy last year he didn't want to run out. Ended up spending $60. We had less than 10 pieces left over. I decided I had enough. I told him last year that we were turning off the lights and using that money for dinner on ourselves this year. Well...Himself is doing his astronomy thing this year during trick-or-treat. I'm turning the outside lights off, going to the master bedroom in the back of the house, and reading until it's all over!
