One afternoon I met a local gentleman who showed me around town, and he said to me, "Only tourists wear shorts here. Panamanians don't wear shorts!" So there you go.
Ciudade de Panamá is delightful in many ways. People there are great. I enjoyed my visit and hope to go again soon.
To those I met, such as Two Guys and Mystery Woman - my spontaneous crew and date at Carnaval - but did not get a picture of because I was caught up in the moment... there is a quote tagged in Casco Antiguo that applies to you: "No tengo Instagram. Mi memoria fotografica."
Actually, that applies to everyone. Salud, Panamá City.
