Sorry for the short notice but we just found out ourselves. Simultaneous nationwide protests against California’s recently passed Proposition 8, which overturns a state law legalizing gay marriage, are set for tomorrow at 10:30 a.m. Pacific (1:30 p.m. Eastern). To find out where to protest in your state and town, visit JoinTheImpact.com.

If you live in a state like mine that also passed an anti gay marriage initiative, feel free to adapt your protest accordingly.

Since there’s not much time, you might need help coming up with a catchy slogan for your sign. No problem — the site supplies a full page of suggestions and photos from protests already held. There’s even a page to brainstorm protest chants. These folks have thought of everything. All you have to do is show up.
