What are your interests? Sports teams are always a good bet if that’s something you like, I guarantee most teams will have a number of queer women on them especially if it’s an all female team or league, and ESPECIALLY if it’s a sport that leans queer like soccer or rugby. If you’re not into sports, hanging out at coffee shops, thrift shops, plant shops (not even kidding) are great ways to meet queer women. Also art classes could be an option. As for the apps, don’t know how popular Her is in the city but it’s all gay/bi women so may weed out the couples looking for a third.
