Well, you don't really tell us what you're looking for in where you live. What kind of place makes you happy? What kind of place makes you hate life? What kind of people do you like to live around, what kinds of things do you like to do? What do you feel makes a city/area great?

FWIW, PA pretty much has it all, from wooded rural areas to a number of different big cities, so I think where in PA (if PA at all) will depend on your tastes.
