I understand that it was only a matter of days after The Mission Bicycle Company opened their store front in San Francisco's Mission district that someone welcomed them into the neighborhood by presenting them with a brick. Now seeing as it was after hours, and assuming the individual in question couldn't fit the brick through their mail slot, they did what comes naturally when one finds themselves in a gift giving frenzy and made quick work of their window.
Now say what you will about their business plan, or that they are the new kids on the block (man, that kinda shit would never fly when I started riding fixies 'back in the day' (i.e. one to four years ago) or that they are somehow exploiting the 'scene' (if Don Fisher of The Gap fame started marketing fixed gear bicycles, then I would happily direct you to the pile of bricks in Danzig's front yard)

but the fact of the matter is, these are people with a savvy business plan who have a soft spot for fixed gear bikes. Don't like it? Don't buy one, but from where I stand exacting some kind of low rent street justice is just about as gutless as you can get.
