After securing a Telcel SIM card at MEX airport—which I thought cost 129 USD until I checked that “$” is also used for Mexican peso—and making sure it was gonna keep me going in the city, I booked an Uber to Biblioteca Vasconcelos for $91.96 and stepped out in ~23 minutes, muttering the palabra one has to know in the Spanish world: Gracias!
Before COVID-19 forced countries to close borders and only allowed the entry of citizens and residents, I just arrived in Colombia for a 12-day trip without a Yellow Fever vaccine. Don’t get me wrong, I had it planned way ahead and the confirmed cases were only few then. And in retrospect, I barely talked to anyone and constantly sanitized my hands from time to time. #defensive
