A turnout on Golf Links Road in Oakland.
The hashpoint is on a turnout along Golf Links Road in Oakland, which has an exit from I-580, so it's really easy to reach. It's also not a big detour from my usual commute home, so I got it on the way. Unfortunately, I got there at night, and wasn't able to get a picture of anything but the GPS unit, and even that wasn't very good.
I was really unprepared, but left an empty coke bottle with a piece of cardstock inside, with xkcd written on it.
I've posted a KMZ file of this expedition here.
