Think guerrilla gardening

The term guerrilla gardening was first used in New York City in the early 70s, but the concept of gardening on someone else's land without permission has been around for centuries. But thanks to the internet, emails and blogs this green movement seems to be moving across the globe at a more rapid rate these days. Is there a derelict patch of land near your home or places you frequent that needs some love? Gather friends and have a late night guerrilla gardening event.
