We only got about 50 kids at home this year, but I was out walking the neighborhood with the kids. And an insulated stainless growler full of mulled cider, and a bottle of apple jack, and some whiskey, and some spare cups for random parents we ran into. Then we ducked into the neighbors for some beer because we ran out of drinks.
The kids ran from house to house for 90 minutes or so, while we hung out in the street socializing. In the end they asked to go home because they were too tired and their candy bags were too heavy (I refuse to carry them, except on the way home).
