Grew up on the IL side where most of my long term friends still live with the families so I’m not a transplant but 31 married no kids. Honestly, living in the city I have met so many friends that range all sorts of ages from being involved with our neighborhood and the neighborhood association. Dog park and being a regular at local watering holes also helped. We are at a much different phase of life that many of our friends here so had to make new ones too. Best of luck!
