București×San Juan
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: București uses the RON (lei) and San Juan uses the USD ($). Language shifts too — Romanian in București, English in San Juan. Cars drive on the right in both, so rentals feel familiar.
