Moved to the seacoast about 12 years ago knowing nobody. First thing I did was join a men's basketball league. I've met a ton of people from my town through that. Look up adult/coed sports leagues to join in your area on the rec center site or http://www.mysocialsports.com/leagues. I also train BJJ where I've met alot of good friends that i hang out with outside of class. If BJJ isnt your thing i think crossfit or yoga would have similar results for meeting people. You can also join your town "official" or "unofficial" Facebook group and throw up a post of looking for people interested in "X". It feels awkward but don't be afraid to strike up conversations and put yourself out there, as adults i think we are overly cautious in putting ourselves out there.
