Have you ever heard about the Rebar Project?

If not, I will tell you about it. The Rebar Project is a group of artists, designers, and activists based in San Francisco . One of their projects is called Park(ing), where their mission is to provide “temporary public open space in a privatized part of town”. What they do is turn a regular vehicle parking into a small temporary park where just like in a metered parking you can feed the meter and then that space is yours for that period of time to sit in a bench surrounded by green space. I think the idea is genius, and I hope that their project spreads around the world and becomes contagious!
