"What time is it?"
It's clear why most Icelanders use 24-hour time. In the heavy mist around Reykjavík, it's impossible to distinguish the time of day, aside from the deepest hours of the night. From the thin light in our basement-level accommodations, even that wasn't enough.
Jet-lagged and sleep-deprived, we completed our supply mission with generous help from Reykjavík Roasters, which serves its own roasts as espressos and pour-overs, as well as a variety of teas. Over the course of the day, we must have tried them all. The baristas recognized us each time and made new suggestions.
Despite the heavy caffeination, we failed to stay up for the Independence Day celebrations and crashed the instant we got to our AirBNB around 15:00. Roughly 18 hours of heavy sleep followed, broken only by a brief photo-walk around midnight to see Hallgrímskirkja in the misty night.
Does Iceland celebrate their independence with fireworks? We couldn't tell you.
