  1. I am interested in contacting Ryan regarding the adaptive re-use of a public golf course, my UCLA Landscape Architecture thesis (2011-12). Can you please advise? It appears he may be a great resource for this abstract.

  2. We are campaigning to have two streets in our neighbourhood closed off to create two cul de sacs and a small neighbourhood park.
    We call ourselves ‘Supporters FOR the Park’ and feel it would make a huge difference to our area. I am particularly interested in how it will effect families and children. Do any of you have any helpful material on parks and children? The advantages feel as plain as the nose on your face, but any studies, websites or pedagogy that might back them up would be much appreciated.
