The PFDS is a non-profit organization which promotes disc golf within the greater Pittsburgh area of western Pennsylvania. Must-play courses included Knob Hill Community Park (par 54-61); Deer Lakes Park (par 66) and Moraine State Park (par 66).
Hit up Montiel in San Marcos and Emerald Isle in Oceanside. Both are like 40min north of downtown and Emerald is a good course set up on an executive Ball golf course. Sun Valley is in San Diego I think but I don't know much about it.
