CULTURE, Halloween trick-or-treaters [FP]

I didn't provide candy for the whole trick-or-treat window, but here are two observations.

1. All the kids trick-or-treating my house were Black. Are there really few non-Black kids in north Forest Park? Or are "White" kids non trick-or-treating in north Forest Park for a reason?
2. Few of the trick-or-treaters wore costumes.

How about other parts of Proviso? Do trick-or-treaters wear costumes in your 'hood?
