Hate on hill bombing all you want...this photo is way sick. Riding in SF is something you just have to do. Its similar to riding in any big city with high volume traffic, people that would rather run you over than be late to yoga class and plenty of things to throw you to the ground. The Muni tracks will destroy you. I love San Francisco for what it is and riding there is a swell experience. Pulled this from the Maca blog.
