A bus driver alerted police about a missing tourist on his sightseeing tour. The excursion to Eldgjá volcanic canyon stopped for hours while the search was carried, however, the search was called off at 3am when it turned out that the missing woman had been on the bus all along and even participated in the search for herself. Before reentering the bus after the stop at Eldgjá, the woman changed her clothes and freshened up, resulting in the other passengers not recognizing her.
I remember her! With an awfull blue dress? Not me! :)
