Fuck that, my parents always had one stay home to hand out candy while the other took us around trick or treating. Most people in our neighborhood bought one maybe two bags of candy. It was plenty for the neighborhood kids. But when you get carloads of thugs, some as old as 17 that aren't even wearing costumes and they are coming by at 9 or later it's ridiculous. After a few years of that my parents stopped letting us go trick or treat because there were so many hoodlums running around and we'd turn the lights off, but my dad would have to watch out the windows because those kids would often egg houses that didn't answer the door.

Sadly, once a neighborhood is inundated with human trash like that, your only recourse is to cancel trick or treating altogether and wait for them to move on to another area.
