Nearly 40 years after the landmark Roe vs. Wade Supreme Court decision legalizing abortion nationwide, forces on both sides of the contentious issue lined up this weekend for marches in San Francisco only a few blocks from each other.This Sunday, the city played host to both the West Coast Rally for Reproductive Rights at Justin Herman Plaza, put on by the Bay Area Coalition for Our Reproductive Rights, and the Walk for Life, which began at the Civic Center and then traveled down Market Street ending at the very same plaza as the pro-choice rally.
