If I learned anything about running a league, the groundwork was laid directly from these guys. Talk about a big following and great group to play with.
Basket Cases Tags are hosted Sundays at 930am. Generally, they're found at Sergeant Means in Olympia Fields, but they have been known to travel every few weeks. Check FB or UDisc for schedule info.

A strong presence in the Region with years of experience running leagues and tournaments, these guys have put on shows and consistently delivered with successful events.
Their home course is Lemon Lake County Park and they host random doubles there Fridays at 5:30PM. If they're hosting a tournament, you've got to make sure you attend. Their 2024 event at Lake County Fairgrounds was 10 out of 10!

Fore 6 Three is a league that does things right! Playing any course with a 463xx prefix to the local zip code (and Merrillville 46410!), they bring life to every course around here with an awesome group, excellent prizes like large cash CTPs, and a rolling Ace Pot.
They run a spring into a summer schedule and a summer into fall schedule with separate overall points/prizes.
Check their Facebook/UDisc page for the full schedule on locations, but you will always find them Sunday mornings at 8am!

The club maintaining Glenn Christopher Nicholson Memorial Course at Countryside Park in Portage, Indiana and running leagues Sat and Sun at 3pm.

Officially registered as an LLC, they are prepared to sponsor, host, and provide for the disc golf community and are currently designing a new course for the Portage, Indiana area.

These are the founders of the courses we all call home in the region. If there's a basket within 60sqmi of us, they likely had something to do with it!
Leagues are hosted by them almost daily at 6pm during the summer. River's Edge is the main course used, rotating occasionally to Riverside, Marquette, Forsythe, Pulaski, and DeYoungs Grove. Add Ski on FB or follow their link to see location and times specifically.

Our friends just at the far east of the region still. This group of guys hosts the tournaments at Indiana's Rogers Lakewood (Rated 6th out of 280+ courses in the state!).
That's not all they host, with leagues on Mondays, Wednesdays (rated!), Thursdays, and Saturdays as well! Check FB or UDisc for specifics on when and where they are playing.
