Here in SF, you can get a ticket if you're parked on an incline and your wheels aren't curbed. What I want to know is, what if you curb your wheels the wrong way? Is it a double ticket, or do they give you an 'A' for effort and let it slide? I see wheels curbed the wrong way all the time. It's not that hard! I don't have a good way to explain how to turn your wheels in different situations, but intuitive things are often hard to out into words. Just do what you have to do to fight gravity, people! or look at the other cars on the street and make your wheels do what the other wheels are doing. Good luck!
