confirmed: "Flames consumed the set of the long-running TV series “MASH.” #woolseyFire

This was where they filmed the TV and/or movie scenes ...it was left as a historical archive..an outdoor setting that the public could hike to. .... for free ..  I did the hike once..not too difficult but not accessible to handicap...sounds like it got decimated by the fire
