Very cool vid!
Reminds me of a tourney (OZ Tour event) I played out in Colby, KS where a temp course (at Colby Community College) was set up adjacent to and including some of their permanent course, Villa High DGC. It had urban elements other than playing near busy streets. I believe this was either over Thanksgiving or Christmas break so there were no students/faculty or cars present. Very enjoyable golf with a very different feel. The course was not near as tight as the one in the vid though.
Something to consider/think about as a safer area to play...especially when no one is around.
