RSVP to Bornhack 2018
It’s a hacker camp on the island of Bornholm, in the Baltic.
I visited the inland last year in my boat. We made a short cycle tour through the island, which is forested and has nice gapahuks. I wouldn’t mind going back. I will make sure to take food with me though - it is expensive even by Scandinavian standards, and so are the harbours.
