Once we were directed to the clerks office, by a same-sex couple that just got married, we took our application and number - A058 - and waited in line. Within minutes we were called to the front desk and greeted by one of the friendliest city empoyees ever. After reviewing our application, and looking our our drivers licenses, she informed us that we were the first couple from Pennsylvania to get married in San Francisco. I guess that makes us "Keystone Pioneers" :)
Here is a picture she took of us being sworn in.
