Early Saturday in San Francisco there will be another massive protest against Proposition 8's passing. But this time it will be a nationwide event, with demonstrations in each state. (Another one, you say? Well, Dan Savage has a great op-ed piece in The New York Times today about how Prop. 8 can get worse, much worse, if we don't overturn it. And quick.)

Join The Impact - San Francisco begins goes from 10:30 a.m. - 12 p.m. at San Francisco City Hall (1 Dr. Carlton B. Goodlett Place). For more info on combating Prop. 8 and further discrimination in state of California, visit Stop8.org, Join the Impact, Protest8SF, or get Twitter updates here.
