Have you picked up a printed starter card from any of the Rebus Round organizers? Unfortunately, the map hides an error, Lyckebolaget (no. 22) has ended up in the wrong place. In all digital maps however, the selection is in the right place.
The Lyckebolaget is located south of national road 70 between Lådö and Ljung. If you come from Enköping, turn left at the sign Wiggeby and drive 500 meters on that road. Vice versa you turn right if you come from the north. The address is Enköping Spring Church Wiggeby 24.
If you happen to end up at the spot marked on the printed starter card, a reference to the correct spot will be there.
Good luck finding Lyckebolaget!
