From Sarah we have a link to a site with a wonderful concept.
Freewayblogger.com teaches you how to make Freewayblogs, one of the last outlets for individuals to express themselves to the masses.
HOW TO:
Freewayblogs are cardboard painted white and lettered via overhead projector. Corners and anchor points are reinforced with duct tape (at least two layers) and pierced with coat hanger or bailing wire. Wire can be quickly wrapped around fencing and secured with duct tape.
