Here is a small guide to going to demonstrations or public concerts at the Town Hall Square (Rådhuspladsen) in Copenhagen:
1. See if it's something for you.
2. Look for your friends.
3. Park your bicycle.
4. Hang out with the one you love.
5. Make more people come over.
6. Leave. If with a cargo bike, make a peloton. The more, the merrier.
