If State Parks Close, What's Left?
The state parks that are proposed to be cut are quite beautiful and very popular--still, if they close, it's not like there's nothing left. State parks make up 23% of the Santa Monica Mountains National Recreation Area, leaving a good amount of acreage to the National Park Service and another state park agency local to Los Angeles, the Santa Monica Mountains Conservancy (note that there is a considerable amount of private land within the Nat. Rec. Area, too).
And beyond the National Recreation Area, there's the Angeles National Forest (which hold 70% of open space in LA County), the Simi Hills, Griffith Park, LA County Regional Parks and other properties run by the Mountains Recreation & Conservation Authority, who runs the website LA Mountains. That's a whole lot of unexplored choices for many Angelenos.
