This whole issue is a tough one. Its kind of romantic to play a sport very few outsiders have heard of, you can get up on a Sunday morning hit a course and play out in nature completely free of green fees and a ton of people.
With respect comes a lot of things disc golfers today may not really want.
I respect those that play the game and are truly passionate about it, but be happy for now with the charm our sport holds now. If it gets big and Nike comes out with a disc golf shoe and mainstream attention soon follows, then enjoy that too.
