Yes, it's something I always wanted to do and you get a different perspective when living abroad. What did you do while in Norway? Would be good to hear about some of those places.
I worked with my dad installing and maintaining newspaper printing presses in Norway and Denmark. We drove from Harstad in the north down both Sweden and Norway many times. Odda is a nice little town if you get chance to visit with an old hydro plant turned museum just down the road. You get some great views on the drive in if you come over one of the mountain passes. We came in via Hardanger Fjell, in convoy with the plough in the last week of April. That's the area where the "Heroes of Telemark" hid out from the Nazis and is also where they filmed the battle of Hoth scenes from Star Wars. If you head into Telemark you can find the old hydro plant where the heavy water plant used to be, you can then follow the route of the railway down to Tinnsjøen and see the train ferries where one was sunk to keep the heavy water out of German hands. If you drive around like we did (rather than fly everywhere like the natives) you see lots more, the Stavekirke are great and I vividly recall coming down the E6 south of Salt Fjell and watching a stream become a raging torrent as it dropped 1000 metres towards I think Mo I Rana, what caught my eye was it's colour, it was like liquid Sapphire. Maybe it was the light coming off the snow and such like, not sure I'll ever know.
If you get far enough north you can visit the Adolfkanonen, the world's largest land based gun, built as part of the Atlantic wall in WWII. You can also visit the war grave in the nearby church where lay hundreds of POWs from the eastern front who build the gun emplacements. In fact if you've roamed that far north you will have passed along the Blodveien, a section of the E6 that along with the railway up to Bodo was built using slave labour by the Nazis. The bodies of many are still under the road and there are memorials all along the road side, some official and others carved by comrades of the fallen after it happened.
If you get up to Tromso (as far north as I made it) there's quite a few things to see, including The Polar Museum which has Roald Amundsen's ship on display as I recall. At that point north you're also at the focal point for the Aurora Borealis, head inland away from the city lights and if you're lucky you'll get quite a display.
That's just what I can recall off the cuff now, not even dented what's up there.
