Political Signs used to Build Raised Garden Beds
Saw this interesting article linked in the Texas Gardening Forum. A non-profit group called "Food is Free" is using old political signs to build drought-tolerant, four-by-four gardens in people's front yards. The project leader says the wire stands of political signs make great tomato trellises, and the signs themselves are perfect as liners.
Here is a link to the news article and video, and below is a link to the Food is Free website. The Guides and How-Tos are on the project website under the "Resources" tab.
