It's quite easy to get around in Oslo without a car. There are lots of busses, trams - and the subway, which doesn't only go underground. These can take you either downtown, out of Oslo or to the opposite side of Oslo. Usually, they go every 15 minutes, which is quite good. In the weekend you can find night busses to get you home in a less expencive way than by taxi.
We have run this blog for quite a while, and feel like we need a break to do other things. We will still post photos, but not as often as before. Hopefully you will continue to visit us from time to time. :-)
