Do you like any particular musical groups? I ask because I recently joined our local Parrothead club (Jimmy Buffett fans) not because I am a huge Buffett fan, but because I am going to my first Buffett concert and I wanted to buy a seat on their bus (instead of driving). As soon as I joined, I got inundated with emails about all their group social events -- meet ups at bars, beach trips, trips to other concerts, dinners, charity events, picnics, sporting events etc. They seem to get together 2-3 times a week. Parrotheads are pretty social Margaritaville types, but there are probably other similar groups for any type of music.
Similarly, our local ballet company has a "Jete Society" - a young professionals group - and a Women's Committee. Both of them meet up for social events, ballets, concerts, opera, and fundraisers. Maybe something like that could exist in your location?
