I am not at all surprised by Illinois, as it has a very large Polish demographic. I’d venture to say that Serbian would be not all that far behind Polish in Illinois. In my immediate neighborhood alone there are several Serb families, but Poles still have more. The muzz are moving in in droves, though, but they are still mostly to the south of me; however, there are two muzz families within three blocks of me, and they are SURLY, and they hate dogs. Walking your dog by their houses elicits some very hostile looks.
Yep, every time I go to Chicago, I look forward to getting some good Polish food.
Most Chinese immigrants HATE dogs, too. I was walking our cute little Goldendoodle puppy out at the Charleston Slough in the south San Fran Bay a couple months ago and came across a Chinese woman walking solo. Little friendly puppy started moving toward her to say “hi” and she totally freaked out, waving her hands, back pedaling as fast as she could while still waving her hands in the air. It was all I could do to not crack up on the spot.
