Parking in the winter in Minnesota is kind of like driving in it; depending on how much snow there is, it's really hard to tell where you are on the road. With that said, if your park job is a little off, it might not be 100% your fault. Well, that, or you just don't care.
But, if you are one of those that don't care and you end up parking on the sidewalk, you might just get a "thank you" note like this one.
