As soon as we walked off the plane into the airport in San Jose I felt comfortable because the floor tiles were shiny and polished, the air conditioning worked and the walls were not peeling paint but were displaying scenes of the country we were about to visit. Everybody smiled, from the customs officer to the taxi driver who delivered us to our hotel for less than we expected to pay without any haggling or confusion. “Welcome to Costa Rica,” everybody said, because it was obvious that we were newbies with our pale northern tans, our tagged luggage and lack of common currency. No matter, US dollars were pretty well equal modes of payment like the local Colones and accepted everywhere. We were not used to think in terms of tens of thousands for a meal and it took a mental adjustment to figure in the local currency, which basically was 500 Colones to every US dollar, mas or menos.
