The Return of Harold Bratback

I am trying in vain to arrange a few days holiday in York, a city I have never seen.

I wish to pay a visit to the birthplace of Harald Bluetooth, the first Viking to use Bluetooth technology to keep in touch with the other rapists & pillagers back in Denmark.

Did you know that symbol was a combined pair of Nordic runes (not ruins) the latter being the Viking gift to these shores.
