While people generally think of gentrification as the process wealthier residents displacing poorer ones, it's also about revitalizing retail/commercial corridors that have become a bit, well, hellish. When I first got to the urban hellhole there were only a few locations I would think to direct visitors to, not because the city had nothing else to offer, but because areas were a bit spotty if you didn't have a destination in mind. Now there are many more.
