"The Things to do are: the things that need doing, that you see need to be done, and that no one else seems to see need to be done." - R. Buckminster Fuller
The cheapest and easiest way to get a message out to a whole lot of people is to paint a bunch of signs and put them up on freeways.
(Signs posted in Los Angeles, San Francisco, Berkeley, Sacramento and Marin)
The Melting North
These signs were made with about a dozen bike boxes, an overhead projector, duct tape, and about thirteen dollars worth of paint.
All of them fit into the back of my Prius.
While large signs on overpasses make for good photographs, they tend to come down much sooner than smaller signs placed along the peripheries. On the plus side, the people who take them down are rarely motivated to move them very far, so you get to reuse them a lot. The sign above stayed up into the evening, but was down and torn in half when I came by the next morning.
It was torn so neatly though that instead of taping it back together, I just posted the two halves on a different overpass. Posting method: place cardboard against fence, stretch a couple of bungees across, duct-tape top corners, walk away.
Here's how it looked from a distance.
Again, it's the signs placed alongside the freeways that do the heavy lifting: they stay up for days or weeks rather than hours.
Signs placed on hillsides next to flyaway ramps stay up forever.
I do love how they look on overpasses though.
The right to post political speech in the public arena is one of the most protected rights we have. Since January 1st I've put 510 signs up on freeways without any hassles from authorities. During the Bush administration I put up something like 5,000 of them.
I have never been arrested.
