Ehh, I'd bet there are a lot of "fastest growing sports in america" that would dispute this. Been to a women's roller derby event lately? And unlike us some of those ARE getting 1,000+ spectators at their events.
I know its seemingly logical here that people on this forum assume everybody and anybody is finding their way to a disc golf course. You play disc golf, you talk disc golf, you spend inordinate amounts of time on disc golf related websites like this one, but there's a big, big world out there that has no interest in our passion, and does have interest in other passions, many of which are trying to supposedly "go mainstream" like we are. Some of which have much better chances to get on television that we do.
