You can buy through this link but you won't be able to pick them up until game day. There is an email for the guy heading it up. It is through the alumni association. Tickets are 45 dollars and include access to the tailgait. You can also buy tickets at the cal website for 70 dollars or on stubhub. There was 1 person selling 10 tickets in the BYU section on stubhub and there are a lot available in other sections.

I don't know if this game will be a sellout. I debated whether to buy now or just wait. I ended up buying the 45 dollars tickets and will see what happens.
