never heard of these guys, and it sounds like a pretty farfetched idea, but they have quite a list of partners and have done some larger scale stuff in the past.

We anticipate having over 10,000 volunteers, so we will undertake a very large-scale effort to remove blight and create beauty, establishing safe and inspirational pathways for kids traveling to and from school. We will also renovate homes in the surrounding area and demolish a few burned houses. Mann and Henderson Elementary schools will receive some love too. We plan to do light “facelift” projects at these locations.
