I'm going to throw Ann Arbor area in the mix. Recent upgrades and expansions in a couple courses makes a difference.
The Stars
Hudson Mills 48 holes, good quality
Independence Lakes 36 holes, terrific quality
Lakeshore 36 holes, solid quality
Kensington 36 holes good quality......plus a part time 18 holes with Toboggan, top quality
That is 174 holes of really top notch disc golf
Supporting cast
Rolling Hills 36 holes, plus a putting course
Gulch 18 holes
Northridge Church 18 holes
Lyon's Den 18 holes
Cass Benton 18 holes
All within 20 miles of one another. There are about a dozen additional courses that are not destination courses.
Good eats, entertainment, breweries and attractions
A chance to play with BogeyNoMore!!!
