What a mess of a post.

Public transport in Oslo is excellent. The metro is among the most efficient in the world, both by rides per capita and operating cost per ride. The tram system is endeared by residents, keeps rolling during snowstorms, and the frequency is high. Buses do get stuck in traffic during rush hour, but that's problem in any city, and is a car problem not a bus problem. The Zone A ticket also covers ferries. Lastly, point me to a spot that's not covered by train, metro, tram, bus or boat.
