San Juan×București
Three numbers. The ones that decide the meeting.
When the world meets at work.
Read the day in both zones.
Crossing the border. Money, language, plugs.
Money changes hands at the border: San Juan uses the USD ($) and București uses the RON (lei). Language shifts too — English in San Juan, Romanian in București. Cars drive on the right in both, so rentals feel familiar.
