Stepping outside The Independent, Philadelphia feels distinctly European in scale with its colonial architecture, brick homes, cobbled streets and the green squares that punctuate its neighborhoods. It’s a city where strangers often say good morning and where millionaires keep a scrupulously low profile, even as they’re raising the city’s skyline. Visiting this livable, diverse city with its patchwork of cultures isn’t merely a lesson in our country’s history — with its new bicycle lanes, hybrid buses and green spaces, it’s also an authentic glimpse into its future.
