I will not debate climate, but as of today I believe the similar of the summer of 2018 will not occur again in my lifetime. We have been sailing in sunshine and warm weather for 3 months.
Visited Copenhagen medio August from an anchorage northeast of town. And decided to see Freetown Christiania. With the sunshine and warm air my mind immediately went back to the Caribbean small islands. The area really appeared laid back and relaxed. The smell of pot. Only a few cars to be seen. (But quite some tourists like myself).
Christiania has managed to establish itself as an alternative society in the capital Copenhagen, and exists in some kind of truce with the authorities.
