At the moment I'm just finishing researching the origins of a 3-hole, 720 yard free golf course with artificial grass greens on Harris Hill near Elmira, NY.
It turns out in 1973 one J. Arthur Kieffer, Chemung County grounds official believed a nine hole public course was needed to compliment the nearby amusement park and Air Gliding facility and designed 3 holes that cost $1,200 (originally w grass greens) and built with local youth corps. By 1977 Kieffer (without full authorized approval) had expanded the course to 5 holes, still without funding approval.
Over time, Kieffer's 9-hole dream was abandoned and the two added holes were as well but today people just go out and play the three remaining original holes for free fifty years later.
I haven't played there....yet.
As to the original question, you tell me.
In case there's any remaining doubt as to my geekdom, here's our hero below.
