NUUK, Greenland — A dark SUV pulled into a shopping center illuminated by the midnight sun. Tour operators René and Ulrikke Andersen jumped out of the vehicle and approached a pair of tourists with an offer. Two people had signed up for that evening’s whale-watching cruise, but the guides needed to fill a few more seats. Were we interested in going?
Yes, we answered, but we are those two guests. The Andersens sped off on their quest to rustle up more bodies.
