We found out the hard way (sooo much leftover candy) that kids in our neighbourhood don't trick or treat in our neighbourhood. I don't really know where they go - somewhere with more single family homes and fewer townhouse/condos maybe? But after some keen internet research, I am wondering if maybe they all go to a trunk or treat?
A trunk or treat is a family event usually held by a community centre, school or church. Folks gather in a community centre or school parking lot and pass out candy from their tricked-out trunks. You can pick a fun theme for your car (luau! Star Wars! NASCAR!) and decorate accordingly. It's a great way for the little ones to get together and get some candy in a safe environment and it gives the adults an excuse to dress up both themselves AND their car.
This kid and his dad decorated their car like the Disney movie Cars - very meta.
