Precious, precious parking

In the densely populated areas of San Francisco, parking is a scarce commodity. And if you're lucky enough to have a garage, the last thing you want is someone's inept or inconsiderate parking to block your way. The owner of this garage makes that point with delightful eloquence. By the way, when I took this photo, a car was parked so as to block the driveway completely. C'est la guerre.
