In most major cities (Miami excluded, of course), there are plenty of public transportation options. And with train stations come art, music, and hoards o' hipsters. Think of New York City subway tunnels on any given evening.
Last weekend, the Purple Line pop-up transit station showed Miami what our city would be like were we to have options other than overpriced cabs and a people mover. The pseudo-train station concept is a collaboration between a whole host of local groups and individuals, and it took over the space underneath an overpass on NE Second Ave. this past Friday and Saturday with art, music, and eats.
