Amongst these trick or treater's were several Polish families.
I wondered if trick or treat was popular in Poland and they were just carrying it on over here. But a Google search when I got in revealed that trick or treat is not popular or even particularly celebrated in Poland.
So what I saw on the street tonight was integration. Immigrants integrating into our way of life (and quickly - they haven't been here long of course).
This is, in my opinion, how it should be. Others immigrants take note.
Hats off to the Poles (witches hats)!
