Eastern Park. Davenport, Iowa. It's the first course I ever visited/played, learned about my disc golf community, so it holds alot of sentimental value to me. It's not a very difficult course, wide open holes, average distance is 350ft but fun nonetheless.
Toboggan. Ann Arbor, MI. Another course that holds a great deal to my heart, I won my first BIG event there as an Amateur and a Pro! It has distance, elevation, very open to unleash big shots but with the OB added in recent years you now need accurate distance to score.
