After a bit of the Miss Marples I've added it to the map.

So the ritual burning of the remaining copies took place on the drive from
Stockholm to Gothemburg after the non-Abba meeting failed to take place. The
NME article from October 1987 says the journey was flanked by giant lakes on
both side so they took the E20. The article also mentions they were towed to
Skara after the Jamsmobile got shot at by an irate Swedish farmer.

So towing distance from Skara on the E20. From flicking through panoramio
pics near a dirt track and a farm I?m going to aproximate the burning took
place here.
