I was going to say disc golf too. Disc golf is only as expensive as you want it to be.
Unfortunately I want it to be expensive.
Cheaper than Updog though (the disc dog organization, not a setup for a joke). At least I don't chew holes through my disc golf discs. I have to replace dog discs far more and they're just as expensive as premium plastic golf discs.
Now that I think about it, starting Updog has actually made me stop buying disc golf discs I don't need, because all my disc money goes to the dog now 🤔
