Things have changed in the old neighborhood. There are cool little restaurants and cafes, funky little shops and a vibrant art and music scene. On one side, you have the newcomers— people who came here to open new businesses and live in this trendy neighborhood. On the other side you have the old guard — the people who grew up here, before it was trendy, and have been watching the place they call home rapidly dissolve all around them. For this episode of the Us & Them, we look at the evolution of neighborhoods in Brooklyn, Chicago and New Orleans and learn how all of this change is anything but simple.
