Here's an article that says the same thing about Downriver in Spokane:
"The Downriver Disc Golf Course, at one time a convalescent home and then a garbage dump for some disreputable folks, has provided a local outlet for the growing sport of disc golf, re-established a haven for local wildlife, and provided Simmons with a growing number of customers."
And
Don Dahvee Open Space in Monterey, CA:
"Without frequent use, the park has become a haven for the city’s homeless. What look like empty dimebags and shattered glass of broken 40-ounce bottles from malt liquor litter the park’s grassy terrain. The new course will bring added attention and use to the park. 'The whole community will benefit,' Allen says. 'There’s a negative element in the park, doing things they shouldn’t be doing. With increased traffic, we can help reduce or eliminate that negative element.'"
