Guthrie Park DGC is a 18 hole disc golf course set up along two parks and a creek. It was set up by a boy scout troop, and for a course in the middle of the city it's pretty good.
Pros- Discatcher baskets, kiosk at the start to make sure you know where you're going, easy course for beginners, pretty nice surroundings for most of the time.
Cons- Dirt tee boxes, walking/bike path that sometimes brings pedestrians into your line of sight and you have to wait, beginner course so there's not too much of a challenge.
