After a few hours sleep at the airport, I took the airport train to the city major train terminal.the train was very fast and had free Wifi, so I contact home via Skype. I had to get a PIN for my MasterCard as all ticket vending machines appear cashless, and I've since found most of Oslo is cashless (and expensive)
Getting the bicycle box the 800m from the train central to the hostel was a tiring haul. There was a luggage trolley at the station, but I did not have the coins. I will definitely use on to go back on Friday morning for the train to Motala. Also the bicycle box seems to be ok as luggage in the trains so far, as I have read Swedish trains are not bike friendly (cross fingers for next train)
After checking into excellent Oslo Hostel Central (corner of Kongengsgate & radhusgata), I was glad to put the bike box in the storage room and not lug it any further.
My plan was to wander around. I headed to the harbour, passed the terminal for the Copenhagen ferries, and continued many pleasure boats and sightseeing cruise boats. It was a glorious day, in the mid 20s and I even saw a couple knee deep in the water, which would still be very cold.
Eventually I ended up at the architecturally distinct Astrup Fearnley Museum of Modern Art. There were new units called the Tjuvholmen executive suit.
On the walk back to the hotel I passed the Nobel Peace Prize building. After a chat to home, I had a long awaited sleep.
At 17:00 after a mixup of location I met Kitab and we had a tourist bar bier, then walked the 2.5 km to Christen's place. On the way we passed the Royal Families Palace, which was in a grand park, but had no large fence or tank proof barricades, such as there are the Whitehouse.
After a dinner at a local bar, we checked the time and it was 10:30 and still light. It was a safe walk home thru the park, as many others were out.
It was a long and interesting day in this clean, expensive city.
