It's an odd thing to say in a sprawling metropolis of 2.5 million people, but it's all too easy to be alone in Miami-Dade County. Most of us spend our days shuttling from air-conditioned cubicle to hermetically sealed home via cars with windows rolled up, blocking out our fellow citizens. That's not the case on the Metromover. On the free rail loop around downtown, the magic of public transit happens — Miamian brushes shoulders with Miamian, sometimes even exchanging meaningful words and conversation. That kind of connection inspires another — a social media link to everyone else in the same city you suddenly remember you share. Just look at the number of Instagrams and Snapchats broadcast from the moving cars rolling tranquilly across downtown — all thanks to rapid-fire free Wi-Fi on the cars. Hop onboard, exchange smiles with an actual human being in your city, and share the link to the global network spreading the love. It's a beautiful link.
