I'm with you, Bill...
...I just received the email today from San Mateo County -- beach and park restrooms, parking lots, picnic tables, etc, are off limits. I think the government's only option to save us from ourselves is to bubble-wrap everyone and place us in cold-storage until this passes in a year or so.
I'm going rogue though -- the area behind my home is part of the Golden Gate National Recreation Area, and very few people know about it. I plan on getting lost for some hikes for a few hours each week just to keep my sanity. I can be out for 3-4 hours hiking and maybe see one person (usually not though).
