Yes. Pull/push carts sell well in ball golf, and most people don't even walk. As opposed to disc golf where everyone walks except perhaps a small percentage who are handicapped. Granted, golf clubs are heavier, but carts are the future for disc carrying (at least for the hardcore player). There will always be casual players that don't want to make that kind of investment, but for people who are already spending $300 on a bag, why not spend a little more for the exceptionally better cart over a backpack. Mark my words, in ten years, disc golf backpacks will no longer exist. It will be casual bags, older single strap style bags, then carts, and nothing in between.
