I spent last week in Brazil - São Paulo, Rio de Janeiro, Búzios.
In Rio, we had the amazing opportunity to walk through a favela that has been recently pacified. (“Pacification” is, essentially, the establishment of police units in favelas to drive out gangs and drug traffickers. I did feel morally uncomfortable visiting. More thoughts here) The stacked and squeezed buildings reminded me of the way San Francisco looks from outside the city, each unit a colorful little box that feels like a giant could just reach down and pull it open like a dresser drawer.
I loved Rio. The city is already gorgeous during the day, but it really comes alive at night, when the lights come on and create tiny stars on the horizon.
