Definitely depends on which part of central PA. I've lived in Harrisburg for years and oh boy... is that BUSY BODY CENTRAL. It's pretty much everyone's hobby to be in everyone's business. Now I live in Lancaster and folks tend to stick to themselves. I don't even know half my neighbors and I'm totally fine with that. It's ironic though, because I've also lived in the subrubs of Philly and people kept to themselves there as well. I think Harrisburg is just such a boring city that getting into people's business and being nosy is the only excitement they have.
