Norway is a good country to hitch in, of course depending on location! Hitching in big cities is almost impossible, unless it's weekend. People have a tendency to always be in a rush on weekdays. The main thing to be aware of is the rapidly shifting weather, so be prepared for anything, as they say in Norway: "there is nothing called bad weather, only bad clothing". Places close to small towns are good hitching spots. But do take care of your appearance, as people are a bit judging in this country. Also, you can contact truck drivers and companies to hitch a ride if you're traveling far.
