Visit Stanford University, its campus, the Rumsey map library, followed by a tour of the Google campus.
Please pre-register by adding to your Sched agenda so we know to book you a seat. Further details and bus/lunch tickets (around $50) onsite at the Congress.
First bus of 27 is now at capacity and Google has a limit on how many we can take. If someone ahead of you on the list doesn't pay at checkin, you may move up but it is unlikely. Note other tours still have room.
