The local library might have a book club that gets together once a month. You might be able to find a book club at a nearby college or university. A group of people will form a group and read the same book between meetings and then at the next meeting discuss it. Usually one person will host and facilitate the meeting and typically it is for a book they chose, suggested or recommended.
The local Y or health club offers exercise classes (yoga, pilates, spin) which might allow you to kill two birds with one stone, so to speak. The Y might also have some other programs.http://www.ymca.net/
Your city might have a recreation and/or community center where there are activities and clubs that might interest you and provide opportunities to interact with people.
Sports and social organization also have sprung up in various cities around the country. Some of the leagues or teams are for serious players and some of the other teams are more interested in the social aspect. They will try to steer you to a team that fits your goals. These teams for the most part should be co-ed.

Events and Adventures is another one with branches in various cities around the country.http://www.eventsandadventures.com/
Here's an excerpt of their philosophy/mission:
At Events and Adventures we have a different philosophy - Create a naturally fun environment, where you can relax and be yourself along with 20 or 30 other singles who also are there to have fun. When you are relaxed, having fun, and NOT comparing marriage resumes, it is WAY easier to find someone worth dating. Sounds counter intuitive, but its true. And you get to have a great time in the process.
They will offer different events and if you are interested then you show up and the other people there are interested in doing the event. It might be a hike or a kayak trip or maybe something more urban.
Sometimes there is a musuem or aquarium that you might want to volunteer at to be a guide or maybe there is some other function they need. I know a friend would dive at the aquarium to help them keep the tank clean. They will do training and host some functions for the volunteers, like a Christmas party or a volunteer appreciation. You will probably also get discounts or free admission to the place.
Volunteer Match can be used to find opportunities in your area to volunteer at something that interests you:http://www.volunteermatch.org/
Habitat for Humanity would be another possibility.http://www.habitat.org/
Many people meet others at church. Depending on the church there might be singles groups, small groups that meet for fellowship, a choir, or you could be a Sunday school teacher.
If you are interested in singing, there might be a community choir or other type of singing group. You might find similar opportunities for orchestra or smaller groupings.
There might be local running clubs or cycling (as in bicycle) clubs or masters swim team.
There are also well known organizations that do community service and networking rolled into one: Lion's Club, Rotary Club, Jaycees, Freemasons (and other Mason groups), Civitan, Urban League, Chamber of Commerce, ...
Toastmasters International is available if you want to improve your public speaking.http://www.toastmasters.org/
If you become a full member at a museum, zoo, symphony, or arts center, you will probably get invitations to special events they throw for members only.
Getting involved in something you enjoy whether it is related to physical activity or volunteerism or a kind of philanthropy you will be able to meet other people with a similar passion or interest. You will probably be able to get to know them on a more personal level than at a night club or similar place.
I also hear dogs are great ways to meet people. When you walk the dog, people will ask you about it, pet or otherwise have a way to break the ice with you. Many cities are establishing dog parks which are specially fenced in areas where the dogs can be off the lease and play with other dogs. Just like parents at the playground the owners start talking. Many times you will regularly see the same people.
Local animal shelter and food bank are places that might need volunteers and welcome them.
Cooking classes might be another way to meet people. Some of the nicer supermarkets offer classes. There also might be something like Dinner Done which also hosts cooking classes. There are some kitchen accessory stores that will offer classes. Even if you know how to cook, maybe there is a cuisine or technique (cake decorating) that you don't know or are not as accomplished. Even if you know everything, chances are you might be paired with one or two people, so you will get to talk to them. It will be easy to talk because you have to produce the recipe in front of you.
