I'm obviously biased here, but I'm still a huge fan of both Scranton and Wilkes-Barre, once prominent mining industry centers that are now struggling to revitalize themselves amid a sea of the sprawled-chaos that is much of Pennsylvania! Scranton, (pop. 74,000) and Wilkes-Barre (pop. 43,000) both offer hundreds of historically-significant buildings, yet most are being allowed to decay as newcomers from NY/NJ are flooding into the newer, cheaper housing developments in the nearby suburbs. It's a true shame; both cities have so much to offer to those with a love of unique urban living!
