Sept 1-3, 2017 at the Moscone Center in San Francisco
This is a great con!
I saw Jim Shooter (former editor of Marvel Comics) a couple of years ago. Jenna Coleman from Dr Who was there last year as well. Lots of Cosplay going on and many independent vendors as well.
I live in the Bay Area and I will be there. Let me know if others would like to join me. It would be great to meet!
