IMO you don't go out with the intentions of meeting people you just live your life, get out of the house and opportunities present themselves. For example, I was in the checkout line yesterday at the grocery store and this attractive girl had her food on the belt waiting for it to be scanned. There was not one of those sticks separating her food from what I was going to buy so I asked her if she wanted to buy my groceries. So she came back and said everything but my beer. I then came back and said "you don't like beer?" and then the convo continued. After I started talking to her I realized she had a ring on but that was not the point. The point was I approached and initiated a conversation with a random stranger and who knows next time she might be single. Women whether they are married or not love to flirt and love the attention, the validation. Funny thing was when I was walking out her and her husband drove by me and she smiled at me. I could tell she enjoyed it.
Just live your life, change up your route, linger in public, and opportunities should present themselves to approach.
