Wikipedia's entry confirms the 33rd U.S. Go Congress[1] was held in San Diego, California, organized by the San Diego Go Club, though the retrieved excerpt does not itself state the specific August 2017 dates the pin claims.
WebFetch could not retrieve USGO.org's own preview page (403 Forbidden); its title, "2017 US Go Congress[1] preview," and 1 July 2017 publish date are consistent with previewing the pin's stored 5-17 August 2017 event, though unverified directly.
