“just about every Rav and Posek and Jewish leader in Baltimore was brought up in communities outside of Baltimore”
Josephine,
The fact that these leaders chose Baltimore over other cities is a reason to seriously consider living there. Your need to constantly criticize other communities shows that Brooklyn, the catch-measles-and-get-assaulted-in-the-street capital of Judaism, is truly the perfect place for you. It will serve the world well if you never step out of it.
