ISO Southern Tier Pumking in person in San Francisco FT Cantillion Geueze - not a joke

I’m travelling from UK to San Fran.
Will be in town 23-27 August 2019.
Looking for 2019 release bottles of Southern Tier Pumking.
Will trade in person for 1 x 750ml Cantillon Geueze.

or… can I buy Southern Tier Pumking in San Francisco anywhere?
