While working on laying out this project some friends have come across this Depave website which encourages the removal of products like concrete and asphalt. Reading it has been very helpful to me, I only wish I had found it sooner. At any rate, I wanted to share it with others who might wind up here looking for resources to do what I am doing now. You can find them at http://www.Depave.org

OH, there is a bunch of concrete in my courtyard I wanted to remove and really had no idea where to start. This link is great; thanks!
