Kalen:
Which courses were you unfamiliar with? For me, the only one was that Nullarbor Links in Australia is kind of a real thing. I thought it was just a cross-Outback survival contest of some sort ... apparently, you go from town to town and play one or two holes on the courses along the route. I can't imagine that many people actually do it.
I think I've been to all of them except that one, and the one in Alaska. Was surprised to find that I had built two of them!
Also, the last picture may be of some course in Japan, but it's not Hirono. Kudos to the club that they've managed to keep photos of the course mostly off the Internet!
