I have a friend who is working on a documentary series called 'Redefining Waste' and they're interested in doing a webisode on Nike Grind recycled materials.  Has anyone out these used it for a landscape project or know much about it?  They'd be interested in possibly interviewing someone who has experience with it. Here is a link to some of their work:
