Mainstream means more courses (closest course to where i live is an hour and a half)
If it's a 3hr round-trip to the nearest course, maybe you could do some legwork and get a course installed at a park in your community. Not saying it's easy or a guaranteed slam dunk to get a course put in, but the effort might bring some perspective on what it takes to "get more & better courses" because they don't fall from the sky and just put themselves into the ground.
I would love more mainstream, better courses...
Would courses really be better if every town with a park tried to put one in? What would happen to all these courses when this "mainstream" fad cooled off? More doesn't always mean better.
...greater competition among manufacturers which creates innovation (better bags, or at least cheaper bags). Mainstream doesn't ruin sports, even if there were two golf courses in the world it would cost the same to run a golf course, so the prices would be the same if not higher. Mainstream usually means cheaper.
The competition and innovation part is a good thing but there are already quite a few manufacturers out there doing these things. Cheaper? Maybe, but they need to make money too, and I doubt the respective DG company owners like Dave, Jim, Steve, Chad, Brad (or even Ed) are rolling around in mountains of cash like Uncle Scrooge did in the Ducktales cartoons.
I for sure don't want to see DG companies start to pop up in China and flood the USA market with their crap and their "cheaper prices" to cater to the mainstream demographic who doesn't know any better or could care less about quality "Made in the USA" products and would just buy the cheap $5 Chinova Champion Edition knock-off's
What would make disc golf more expensive by going mainstream, would it cost more to maintain a course? I doubt it? You could maintain a course with one or two people with people paying $5 as an entry fee. Golf is so expensive because because you have metal clubs, Expensive course maintenance fees because of fertilizers and lawncare, and because of property taxes. Disc golf can still coexist in a city park or in the mountains, even if its Mainstream.
