PG&E is not HQ’d in Oakland. I worked for them and KPermante — the latter in Oakland.
Scary place, even over a decade ago. Now, it is no man’s land. Coppers still tell folks to avoid the nearby BART stop if you want to survive the walk to your car.
I flew out of Oakland about a month ago. I have flown into and out of lots of US airports, but this one was crazy. The security was the most intense I have ever been through.
