If all goes according to plan, on Thursday morning at 9:20 President Obama will arrive in the city of Oslo in his helicopter.  That’s thirty minutes after his plane has landed at Gardemoen — not bad going!  I’m sometimes still in the duty-free half an hour after my plane’s landed.  At one p.m. the King will present him with the Nobel Peace Prize at the Oslo Rådhus or town hall (above).  Preparations for the ceremony are underway, causing long traffic tailbacks and the rerouting of public transport. At a cost of several billion kroner all of central Oslo’s manhole covers have been welded shut, just in case of something or other.  We should all avoid going to the city centre for the next few days unless our trip is really necessary. Don’t bother trying to get to work, especially if you commute via the extensive network of sewer tunnels.
