Its a very common spelling error. Don’t google stuff things like Disk golf courses near me, since you wont find Disc golf courses you wont find what you want.
Disk golf->Disc Golf or Frisbee golf
Disk Courses->Disc courses
Where to buy Disks->Where to buy Discs
Disk Cages->Disc Cages
Disk Store->Disc Store
pro Disk Golf Tournaments-> Pro Disc Golf Tournaments
Remember Disk/Disc is replaceable with Frisbee
