Quick business trip to Oslo - I had a couple of hours free, and unfortunately, our conference hotel…read morewas located way above the town. On the plus side, we were within a 15 minute walk to the nearest train stop that took us directly down town. After navigating a terrifying slip and slide walk down a massive icy hill in the middle of a small blizzard, we had just a few minutes wait until the next train came. We bought our train tickets at the hotel, so that was convenient. And apparently using the tickets was on the honor system! We figured out that once you get on the train, there is a scanner that you flash your ticket with. But I didn't see a single person do it except a few stupid tourists like us. Kudos for making it fairly easy to navigate the system.
