Well then, you just need to introduce yourself to yourself. :-)

My old neighborhood was very close knit with lots of neighborhood functions. Our responsibility was the Halloween party. Me ex knew the wives of everyone, VC's, congressmen, academics, and just plain neighbors. The party was so popular that strangers from 15-20 miles away asked to be invited. We divorced and both moved away. I told one of my daughters that I missed the closeness of the old neighborhood. She told me that my ex was the social glue. It's just an ordinary neighborhood now.

My suggestion is to throw occasional, family friendly celebrations (not the standard cocktail party) with a couple of other co-hosts. Family friendly, because the SO's greatly expand the contacts. If there isn't a readily available occasion, celebrate Guy Fawkes day or something suitably oddball. If you make it potluck, it isnt even expensive. It's easy to get a reputation for gatherings of interesting people (except for maybe DC and Manhattan :-).
