Our kids are of such vastly different ages and abilities that it's a painful experience.
Our neighborhood also doesn't have sidewalks and relegates the responsibility to a few streets that are closed off that host Halloween. Note in this situation, however, that it becomes embarrassing: a lot of the adults are also dressed up (some inappropriately for the presence of children)... and many of them are openly drinking. Very strange, and I'm not sure how the neighborhood gets away with this (except that we rent a house in what is mostly the "rich"/"snobby" neighborhood that might be cutting some deals by paying some police officers to be out and about).
We made a deal this year with our middle child (M), who cares about Halloween the most (because of the copious quantities of unregulated candy it generates), that if he was old enough to start shaving off his developing "mustache" (a source of some apparent teasing at middle school) he was also therefore too old to trick or treat.
P doesn't care (the experience is frustrating... costumes are uncomfortable, his electric chair isn't really safe on streets and can't make it up porch steps to front doors).
Lastly: E is too little. She can wear last years glow-in-the-dark "skeleton PJs" and help me give out candy to the few who might arrive at the door... thinking the pickings are good in the rich hood (but being sorely deceived because of the relocation of the hood's own activities)... and eat the remainder.
