Oak Grove Disc Golf Course

In 1974 Ed Headrick, the developer of the original disc golf hole, approached the county of Los Angeles's Parks and Recreation Department with an idea to develop the world's first permanent disc golf course. Before this, Headrick's "courses" were largely chosen at random. Groups of people would pick objects such as trees or benches and play it a they went along. But with the county's approval, the game was about to get more official.

Hahamonga Watershed Park was chosen as the site for the course. The course weaves its way through the park, with shots going around trees and into bushes. The park became a model for how future courses would be developed. One key feature (and a staple of disc golf) of the course is that it is entirely free to play, and often you'll see a mix of families and players "teeing" off, or even just playing 8-9 holes between soccer. 

On the weekends, a disc golf seller will set up in the park.
