I have to say, I do think I've hit the jackpot in this neighborhood. Part of it is self selecting (shitload of singles, so our income is going to dictate a certain housing stock) and nearby university. But we also have some long-termers (20+ years) who are happy to see the new influx.
And I'm sure a small part of it is me now. I want to engage, I'm looking to meet people. So while there may have been people to meet before, I wasn't looking. Now I am, and I picked out a mecca of people within a decade or so of my age and taste in housing!
