I have said plenty of times, get into niche hobbies, some of my favorite
Fashion events-Ratio of women to men is 3 to 1, and 1/3 of the guys are gay. It's a great place to peacock and meet hot women, they tend to be more approachable because everyone is there to have fun and network. Women don't expect to be hit on at a fashion event
Art Festivals-great vibe and also if you are into quirky chicks this is the place
Boat or Yacht parties: If you don't know anyone with a boat or yact you can go on Eventbrite and find events near you, granted Unless you live in a hot place boat season is nearly finished within a month or less
Singles night at church-If you're looking for decent women or women who want to settle down
