Homeless nonprofit Sisters of the Road has launched a postcard campaign to repeal the controversial sit/lie ordinance and anti-camping law, following its resignation from the mayor’s Street Access For Everyone committee two weeks ago.

The postcard asks the Mayor and City Commissioners to repeal these laws with a space at the bottom for people to sign and print their name. Within 2-3 weeks, Sisters wants to have collected enough to assemble in a way that creates “a powerful visual image, and march the cards from Sisters to City Hall.” Here’s the postcard, front and back, that you could print out, fold over, stick a stamp on, and send over there. If you were so inclined.
