I am with the same girl for half my life, so I might not be totally qualified to answer, but I met most interesting girls outside a work context.
That means: on concerts, on hacking camps, in art exhibitions, especially exhibition openings, on film sets etc. These places reflect my interests of course, so I don't go there because of women, I go there because the stuff there interests me. So for you it could be a sports club, a library, an animal rights organization or any number of other, similar places where people of similar interest gather.
The point is: if you want to get to know people (regardless of their gender) exposing yourself to situations where you actually get the chance to meet new people is a good way to increase your chances. Just like your chances of rolling a 6 increase with every roll of the dice.
The important thing is to do it because you like, not because you expect to find women there.
