Is it? I thought that was only in Mpls that you couldn't leave a car running because the police were sick of cars being stolen in the winter. Didn't know about the law re kids in the car. Not that I do it anyway, just suprised there is an actual law on the books.
As for the situation the OP was in, what really kils me is that just a year or so ago, some woman's car was stolen with her baby in it while she was in a liquor store. (Of all places. Wouldn't you just feel even worse.) The car had been left running and seemingly when the theif reaized there was a baby in the back, they abandoned the car. This was in St Cloud and was all over the news here. Apparantly the woman you saw doesn't watch the news or listen to the radio.
I was just saying to a friend of mine that I really wished leaving your kids in the car was not bad parenting. I had a meeting I really needed to go to but had to miss cause I didn't have a sitter and DH was not home. I would have loved for it to be okay for me to leave the kids in the car for half an hour. I missed my meeting.
