I don't even read Penny Arcade. They have concerts, tournaments, a huge exhibit hall... It's a pretty good time all around.
Blitz: http://www.pennyarcadeexpo.com/ It's August 29th-31st. There are some PA kids who ride up on the Coastal Starlight train, but if you did that, you'd have to deal with the PA kids. Where in Cali are you?
I'll be 45 minutes south of Fresno. (central valley)
And I'm surely not riding anything called the Coastal Starlight Train.
