It's no secret that parking in the city is a bitch. So we've enlisted local parking guru and author of Finding the Sweet Spot, David LaBua, to dish out weekly tips on navigating the ins and outs of city parking.

Says David: A couple of weeks ago, my post about your car disappearing generated a lot of email expressing confusion and varied experiences and beliefs about retrieving a stolen and towed vehicle. Many people remember when towing and storage fees were waived if your car was stolen, then recovered. Many people, including some at the SFMTA, the Police Station, and some at AutoReturn were unclear about whether or not any fees were waived. And many people wanted to know when the rules changed. So, I dug a little deeper and found some documents, which will hopefully answer many questions, and probably create a few more.
