“I was told this was because the water was soft, devoid of minerals.”
Very possible.
Or it could just be that you were in WI and they knew you’re a Bears fan?
What do you think, Mauro?
I overheard some guy I didn’t know who also drove up from Illinois talking about how some cop pulled him over, he blamed it on his Bears decal.
This cousin grew up there after his parents moved, someone once gave him a Packer jersey for his birthday. And his ex-GF wouldn’t put out when the Packers were playing bad. It’s like a religion up there.
