Chicago activists working to stop a U.S. attack on Iran placed a sign that read, "No Attack On Iran", over the Eisenhower Expressway during the morning rush hour. The sign was about 25 feet long and thousands would have seen it.

We painted the sign on cardboard using letter stencils. We put the sign up and then left it there. This is called "Freeway Blogging". Others are doing this around the country.
