Gamla stan

Good content of the stages will guide you through the old town nicely. I only had 2 problems, both related to ongoing constructions on site: at one of the stages it was hard to get close to the 'inside' because of it and to unlock the stage. The final was not accessible at all, so the physical cache could not be signed, only approached as close as possible (more on geocaching.com). Also hit some technical bug - when I exited the game and selected not to save it, an infinite loop of errors started showing, so I had to kill the wyg app (on android). Anyway, thanks!
