Keflavik is home to several people (among them a few Icelanders), five cats (one of them black with green eyes), 3.2 dogs, a number of houses and stores, a US Naval Airbase, and the Iceland International Airport. Let's not forget the ghosts, as there are many of them in Iceland living all over the country. Why in Iceland? I don't know. Maybe they prefer cold weather or perhaps they have well-paid jobs as invisible workers in
Iceland sweater factories. Someone from Iceland can probably give you all the information you need. By the way,
The Blue Ghost Blues Band didn't originate in Iceland and they didn't turn blue from the cold. They are from Ireland and chose their name because they play the blues, although it's rather un-blue most of the time.
