Beautifully shot, and important insight.
But, sorry, I have to ask: First, concertina wire? Seriously? What or who exactly scales a stone wall and breaks through plate glass that wouldn't just beat the door in? Alex Honnold's evil twin?
Second: Wouldn't you think that a county as wealthy and well educated as Marin could provide a log sheet with the correct spelling of the name of it most prominent geographic feature?
Third: How the hell do you pronounce "Tamalpais"?
And four: Ok, honestly, anyone else wonder what happens when a fire lines up the Osborne Fire Finder exactly on a corner post of this tower?
