The annual Walk for Life escapade goes down in San Francisco on January 25. Whether pro or con on a woman's right to choose, the annual walk provides yet another opportunity to show the far-right that, actually, San Francisco is a city of tolerance.

Anyway. The group's promo video:
Welcome to San Francisco, Walk for Lifers. We hope you enjoy the assorted sundry of McDonald's and Starbucks outlets the city has to offer.
