This is not yet a waymark category proposal - as a matter of fact, I hope it will never come to that. But: In order to save $70 million, the State of California considers closing 220 state parks, state historic parks and state beaches. Here is the complete list:

I would like to urge my fellow Californians to go out and register as many of these parks as possible under the existing categories "State Parks" and "Beaches", while they are still open. Should it really come to the closure, we can then discuss routing them all over to a new category called "Lost Treasures." This might be the last chance to get a comprehensive collection of pictures and descriptions of something our trusted leaders are about to throw away.
