The only time I even spoke to anyone who knew anything about disc golf was from before I even started playing.
I was in Idaho with my GF for my brother's wedding in 2008. After attending the wedding in Sun Valley, we decided to check out Boise for a few days. During a stroll through Boise's marvelous downtown park, I noticed a couple of solitary people playing disc golf. My GF barely noticed the discs, baskets or lonely players but I immediately recognized what I saw to be this game that I, up to that point in my life, had only a vague impression of based on a 5 second scene from "The Summer of George" not based on any actual experience seeing the game with my own eyes. I had never seen anything disc golf in my life before Boise but I knew, only in the most ephemeral way, though, that it was out there. My level of curiosity about disc golf was so low that I wouldn't even think about it at all unless I had just seen The Summer of George re-run on TBS which happened every 18 months or so since the original airing on Seinfeld 15 years ago.
So we got home to Los Angeles after Boise and it was at least several months before I even mentioned my witnessing of DG in Boise to ANYONE. It was at a party and I only told my friend Cameron because I knew he had a more open mind than most. Reflecting now, I'm sure I never mentioned seeing DG being played in Boise to anyone else I knew because I knew none of my friends would be interested. I suspected that DG had a déclassé stigma and I guess I was embarrassed. So I told Cameron about Boise and he told me that he had, for a while, wanted to try out DG but never had occasion to do so.
That was the first time I ever met someone who even noticed DG. Since then I have never met another person, off the DG course, who knows anything about DG. Part of the problem, I guess, is that I don't advertise that I play. It feels like bragging that you play poker or engage in some other example of marginalia. DG definitely has a subversive/misanthropic/fetishistic rep. It doesn't bother me or stop me from playing. Maybe that's what I like about it.
