No, I'm only going by the first post in this thread, which is that there is a locked gate installed where the road closed sign is located.

With the location of the road closed sign in mind, I'm guessing the gate is installed about here:

36.5961, -118.2063

Hope this is correct... I don't know much about GPS. Caltopo.com also displays the following string above those numbers:

11S 0392099E 4050749N
(what do these mean?)
