Peatonal Florida

This guide to Peatonal Florida in Buenos Aires opens with a hundred-dollar bill worth two different prices on the same block: one at a bank window, another whispered by a stranger on the sidewalk. It traces Argentina's decades-long fight to control its own currency, and the arbolitos, the street traders working the gap between the official and unofficial dollar rate. The street itself was Argentina's first paved road, laid down in 1789 and closed to cars in 1971.
