I haven't been around for a while but this just cropped up in my neighborhood and thought - what better place to share!
My neighborhood is very popular with trick-or-treaters every Halloween. I count them using an app on my phone and last year we reached almost 400 children - it was a gorgeous fall evening and we ended up closing up shop when we ran out of candy at 8:20 p.m.
A neighbor has posted fliers at the three neighborhood school bus stops offering "good" candy to trick-or-treaters who live in the neighborhood - all the kids have to do is stop by their house before Halloween with a parent to somehow get their name on a list, and then Halloween night they just get checked off the guest list, and they get premium candy, whereas all other takers get lesser offerings, presumably.
Honestly, it doesn't bother me that 90% of our trick-or-treaters are from outlying areas - the rural community isn't far from our place, where the kids don't have a safe or populated area to solicit treats, so I just resign myself to the fact that I am going to be treating mostly kids from outside the neighborhood. If I didn't like Halloweening, I'd just shut off the lights as the vast majority of TorT'ers respect the porchlight status.
I personally think this one household/couple/family is causing more grief than needed - their home is four doors down from ours so they're getting the same 350+ kids as us; on Halloween last year I ended up just parking on the porch rather than opening the door every 8.6 seconds and I didn't have time to vet every costumed kid that came a-knockin'. To me it just seems to be more of a passive-aggressive statement against the packs of kids that get transported in than anything else.
