The worst thing about Silicon Valley and the entire Bay Area for that matter, is when the shit hits the fan there are so few ways to get out.
And all of them will be controlled by the zombies.
Even El Camino Real if you hope to go south.
101? Forget it.
Bay Bridge? Forget it.
Dumbarton Bridge? Forget it.
Golden Gate? Yeah, right.
In dire strait some in the east bay will be able to flee through the Altamont if they get out early.
Other than that, you’re screwed.
Mount Hamilton Rd...aka highway 130 will drop you down onto Highway 580 and ultimately Interstate 5.
I’m about a mile from 130 so that’s my ticket out.
